Thank you sir, solved the issue of dropping hammer on reset. Triger fixed: Geissele SSP. Just goes to show that simply because you purchase a top tier trigger, doesn't mean it will work without some light tuning! THUMBS UP/LIKED VID :D
Thanks man! This really worked. I was careful when using the dremel and measured how much i started with. I removed about a millimeter of material. My trigger was having hammer follow when I released the trigger very slowly. So if someone is having double fire and cant seem to replicate it during a function check, try releasing your trigger very very slow.
Thank you. Did an AR 9 build and was getting double fires occasionally. Kept thinking the problem was with my bolt, buffer weight or buffer spring. I was using a PSA lower combined with their lower parts kit. Filed down the disconnector about 5or6 file strokes and problem solved. You saved me a lot of ammo and a possible trip to the gunsmith. Thanks again!
Thanks so much I just had one lower that triple fired it had a really strong hammer spring I just couldn't figure out why would do that and you just saved me thanks buddy
I just built my AR from the ground up with a polymer 80 lower. I put the first 60 rounds thru it today and was having the same issue. I thought it was something I did wrong! I will pull the trigger group apart and try this! Great video thank you!!
UPDATE!!! IT WORKED!!! Thank you so much for the info! My lower kit was from Palmetto State Armory. I had the exact same problem. And that's totally stock, out of the box and into the gun. I dremelled off a bit of the extractor like you showed and BOOM problem solved!
Here's another update. If you file that down just a little bit too much, your safety will not function correctly. I ended up tossing it and getting a drop in. Now she shoots like a friggin dream and no more safety issues.
@@Ammonymity1776 what was the deal with your safety? I have a p80 lower as well, but with a lpk from brownell's, DPMS I think. Anyway, my safety will switch to safe when the hammer is uncocked. I was having an issue with the trigger firing instead of resetting, which i fixed with this video, but the safety thing is still happening. It just goes into safe mode when I'm sure it shouldn't. It won't fire in safe mode, thankfully, but I'm having trouble finding a fix for the issue.
@@ezrabrooks8551 if I would have my safety ON, I'd charge the rifle and when I released the charging handle it would fire! And also, if it was already charged. With the safety on, when I clicked the safety Off, it would fire! Needless to say, that wasnt working too well for me so I put a drop on gold trigger system from ATC
Thank you so much! You showed exactly how to fix my problem. Everybody just says "take it to a gunsmith" but I built this rifle myself so I should be able to fix it
except 7:04 is WRONG. It is legal to shoot doubles, IF the 2nd "bang" comes ONLY when you let off the trigger, or make some OTHER action, after the trigger "pull". Just "triples" are illegal (which is unlikely to be even possible: the next type of trigger malfunction which lets off "more extreme than just turning it into a binary trigger" should be "unlimited" not "triples" unlimited meaning "full-auto"). ~Bill S Preston, ESQUIRE.
@@thebutcherofbenghazi.libya3348 what ever you said, it doesnt matter. Important is the author give us information that is very helpful correcting hammer follow.
Youre welcome. And i know binary isnt illegal...its just not safe when youre trigger is functioning in that way especially when mixed in with groups of ppl that dont exercise safe gun handling
By atf ruling a binary trigger that functions this way is illegal because if you hold the trigger in a sweat spot between both catches and allows the hammer to follow the bolt without being captured.
@@michaeljacques7336 You might want to recheck your information. Binary triggers are not illegal and if it is a binary trigger it's supposed to function that way. Now if you're manipulating the trigger to do what is called a bump fire with your fingers that is not illegal either as you have a legal trigger assembly. It is the way you personally manipulate the trigger to make a bonfire and that the ATF cannot regulate. Also realize the ATF does not make laws only the United States Congress has that authority.
@@gregoryromeu431 I’ll make my first statement more clear. Binary triggers are legal, the way a legal binary trigger functions is that the trigger is pulled, the hammer drops, the gun fires, the action cycles, the hammer locks back again, the trigger is released the hammer drops again and the the rifle fires and we are back at step one. Binary triggers that are sold by manufacturers do not function the way that the modification in this video does. With the modification in this video, it would seem that the trigger is functioning the same way, but when an AR trigger is modified in this way there is a sweet spot, where if the trigger is held in the middle of the pull range, the hammer does not catch the sear, nor is it caught by the trigger catch. This means that as the gun cycles the hammer just swings back and forth following the bolt. This is a major problem for two reasons, one: when the hammer follows the bolt either the hammer won’t have enough energy to set the primer of or the gun will slams fire. This makes the gun function as an open bolt machine gun, you are not cycling the trigger, you hold the trigger in one spot and fire multiple rounds, that’s a violation of the Hughes amendment. Two: It’s also extremely dangerous because you are firing full auto without and auto sear, which means that there is nothing to control the guns timing. If the bolt hangs up an all you will get an out of battery firing and the gun will explode in your face! If you don’t believe me there are more that a few videos on UA-cam of AR sears breaking, where the gun unexpectedly fires a few full auto bursts and then blows up. I say all of this as a trained gun smith and a guy who has made trigger groups from a block of steel with nothing but a set of files. Choose your own adventure!
1) binary triggers are not illegal. 2) that Dremel should not be anywhere near your trigger. 3) if you have a problem get a new disconnector or check that your spring is installed correctly. Do not dremel or file triggers 4) If you want a lighter trigger get a nice two-stage component trigger like the larue mbt2s or Schmidt tool
Realize too that parts here are often surface hardened. Once you kiss them with that grinding stone, you remove the hard facing and then the parts will wear quickly due to the softer steel being exposed.
Binary triggers are legal. Pull and release are two separate functions. Don’t remove material from the bearing surfaces of your FCG. “Polishing” a trigger should not remove material or you’re using the wrong attachment on the tool.
My build has a crappy trigger pull and gets hung up on the reset I go to pull the trigger and it’s like the safe is on remove pressure and go right back on works fine 15 20 cycles then hemmes up again. I am petrified to f with the trigger but might investigate it a bit and see if it will clean up…. Awesome Vid.
It worked!!! Thank you so much! I found this video while looking for “AR15 trigger hammer fail” because I thought the only solution left was a drop-in. Thanks again.
Great video on fixing a binary, but Binaries are 100% Legal according to ATF, NFA Rules only apply when manufacturing or selling a Binary trigger because you need to prove its not a fully auto. No hate but this is common misconception with the law because of the it is written. There are two (Binary) motions to fire the round not a single continuous press of the trigger to send multiple rounds down range, therefor its not a class 3 and no NFA rules apply. However State and Local laws still apply just like for the bump fire stock. Happy shooting and I advise everyone to check their State Laws before shooting binary, and just don't just at the range because everyone is an "expert".
S Trick its not a video on how to fix a binary......its a video on how to fix a malfunctioning trigger. Malfunction= anything that's not 1 bullet per trigger pull. Then reset on trigger release.
thank you again. I did exactly what you said to do in your video and it works perfectly now. shot 150 rounds no problem out of my 10.5 ar pistol from psa. I was having the exact same problem.
It's not true binary as sometimes it's binary and sometimes hammer follow. I just called it binary because I didn't wanna go into a long explanation. Especially since it'd spawn a million questions for the simpletons.
So to sum it up, you messed with a mil-spec trigger, designed not to be a 3 lb. target trigger but designed for combat, and in changing four precision metal surfaces with your Dremel tool, you screwed it up and NOW have fixed the problems you created. Is that about right?
My Dell-ton worked fine before I polished the cap out of the trigger parts . Then I started getting fire's on release. . Followed instructions on your video and it fixed my problem. Thank you for taking the time to help other people with this problem...
You should pin a correction to this video for strong misinformation. It is NOT illegal to purchase, own and or function a binary trigger. It is not classified as a fire arm or machine gun so it is not illegal to manufacture as well. Only parts manufactured for purchase of the intent of creating a machine gun will be classified as a machine gun. Binary triggers still require one action for one shot. Auto Sears however ARE machine guns and require the tax stamp and all that good stuff.
Here in Florida, they are on the bump stock ban list, but the way the law is written is in a gray area. Almost anything could get you in trouble with the law depending on their interpretation. Below is what it says about the bump stock ban in Florida and what all is covered on said ban. Effective October 1, 2018 790.222 entitled Bump-fire stocks prohibited. Reads -A person may not import into this state or transfer, distribute, sell, keep for sale, offer for sale, possess, or give to another person a bump fire stock. A person who violates this section commits a felony of the third degree. The new law goes on to define the term “bump fire stock” to mean a conversion kit, a tool, an accessory, or a device used to alter the rate of fire of a firearm to mimic automatic weapon fire or which is used to increase the rate of fire to a faster rate than is possible for a person to fire such semiautomatic firearm unassisted by a kit, a tool, an accessory, or a device. Reading the definition should cause concern. It is so vague that it could include almost any modification to your firearm. There are many items sold that can accelerate the rate of fire of a semi-automatic firearm, including both handguns and rifles without making them automatic weapons: It can be argued that lightening the pressure necessary to pull the trigger increases the rate of fire to a faster rate than possible unassisted by a kit, tool, accessory or device. Until a court rules on this, understand that you may become the test case if you modify your firearm to fire more easily by decreasing the pressure necessary. Other accessories include, but are certainly not limited to: Traditional Bump stocks Crank fire devices Binary triggers and many more commercially available conversion kits or devices
I wish i wouldve found this video a few years ago. I had the same problem on my AR, went to ar15.com and someone instructed me to do this, so i did, and yes it worked!! A suggestion, please add the title to include "fixing hammer follow"
I have a problem with the trigger not setting after I queeze it. I fails the function test. Now I know the problem. I just don't have the tools to fix it. I know a good smith to take it to. Good to know others have problems too.
Im not getting double fires, but my trigger wont reset. The disconnector wont let go of the trigger unless I pull the trigger forward or actuate the safety on and off.
Yup, this is an old gunsmith technique to file down the bottom of the AR-15 disconnect tail to get proper contact. This was a common problem and knowledge back in the early 80's when SGW was the only other game in town other than Colt...It won't hurt anything to file the entire bottom of the disconnect tail so it will drop farther to contact the sear...
Did a build first time out shot 50 rounds no problem. Went back two weeks later double shots replaced with new trigger still had problems just exactly how much of the tip should you find off not a mechanic. So the problem is with the disconnector
Instant relief at the "ya dont have to buy another trigger," part. Holy crap man my Adams Arms P2 stock trigger disconnect wasn't grabbing the hammer!! So i looked it up and watched this. Honestly kinda suprised to see this on a $1,400 dollar rifle, but hopefully it's just a fluke. Doesn't the US Army get alot of parts from Adams Arms?? Idk how mine passed quality control...Anyways, super informative vid. Learned how a binary trigger functions, AND how to fix it since I live and Iowa and binary triggers are illegal for civilian use here. But knowledge is power!! Thanks for the post, friend!!
You saved me a bunch of money. It only did the double fire when I slowly eased the trigger forward. Releasing the trigger quickly didnt cause the double fire.
Hello all! Im glad this video has been as helpful as its obviously been to so many fellow gun enthusiasts! Id like some feed back on other stuff you guys would like to see. Just let me kno and id be happy to make a video.
Binary triggers are not illegal. ATF has not went against them. It's not a force resetting binary trigger like the WOT. Some states binary triggers are illegal tho
Something and everyone should also know if you do have problems such as this or any other kind of a problem that's causing your firearms not operate properly report it directly to the person or the manufacturer that you bought it from so that they have a record of it and can seek a solution. Also check to find out if there might be a recall on that particular problem or that particular part or firearm. Many times recalls are issued where you can send your firearm in to get it fixed for free or they will replace it for free.
Someone reports you for shooting a double and it's not in a robbery or another crime. There must be a special place in Hell for that type of person. Good video thanks for the help.
Great video! I just finished an AR15 pistol and it dbbl fired! Never happened before and I wasn’t sure it even did until I saw two shells! My bad -first by putting disconnected spring upside down 🤦🏻♂️… I fixed that but now I have a very slight 1/8” pull before trigger actually engages. My best description would be what it feels like when safety is on and you attempt to fire getting that little pull before safety stops you. Any idea what’s happening?
7:04 is WRONG. It is legal to shoot doubles, IF the 2nd "bang" comes ONLY when you let off the trigger, or make some OTHER action, after the trigger "pull".

The Butcher Of Benghazi. Libya indicted me because I'm too stupid to delete my incriminating emails? You dont "gun" much huh. Triples are very possible. Do yourself a favor and quit spreading your "knowledge" until you fully understand.
I have a problem to were it will shoot once then the trigger won't reset just stay stuck in place even with the upper off should I just get a new trigger?
Thank you. My kit was t together correcty but it isn't ihtting the disconnector at all. I haven't shot it because I knew it was going to possibly shoot on its own. I was staring at it and playing with it and realized it was not matching like it should. Out od spec. So thank you. This is exactly what is wrong. You saved me a lot of hit and miss.
Thank you I am having this issue with a brand new 9mm rifle. I did swap out the springs for the JP3.5 springs which I have on three other ars and have not had this issue. Could those springs have anything to do with this issue.
Its not the cap, Its the degree of the step on the sear and the hammer! You need about a 20 degree step, That's what makes the trigger break and makes it feel lighter on pull! Polishing will always makes it feel better on the pull though! And you dont ever wanna use a dremel to do trigger work unless you are a pro! You sand paper and or a very light file! And Binary triggers are 100% legal! As long as its a trigger pull for 1 shot! Or as the say a motion of the trigger on pull and release!
Uh, many states do in fact allow binary triggers, plus those that have an NFA rifle with the three shot burst or full auto are also legal. You don't need an NFA registered rifle if you're using a binary trigger in many states just check your state laws to make sure that you're legal within your state.
Can you just purchase a new disk connector. and if so will the problem come back? And this eventually we're now naturally from where? And is this dangerous?
Hello. Thank you for this video. My trigger just started the occasional fire on the release 2 weeks ago. I forgot and went to the Range to try some new reloads.. My trigger is about 1 1/2 years old. I did some basic polishing when I found out about polishing A while back. So far your video is still a good basic explanation in my search today. I will try this fix. Thank you again.
My DPMS started double firing exactly like this after about 200 rounds. I have to release the trigger in a very quick exaggerated fashion to get a proper trigger reset and avoid double firing. Good info, I’ll try it out
How many AK's have you built? The biggest prob with the low end milspec triggers are that they are just that....low end. Also if youre building an 80% then youve got to understand that the trigger/hammer pin holes will not be exactly the same on every lower built, due to tolerance stacking between the hammer/trigger holes as well as tolerances with the FCG.
The military check after cleaning and re assembly should let you know if your AR is going to go full auto or double tap before you go to the range, I just cannot believe what I have seen on this video and so many have done something similar. The systems check is easy, empty gun, charge or cock the hammer, pull trigger on empty chamber, hold trigger down, charge again, let off on the trigger, it should reset, at this point it should work unless you have removed metal from the surface hardened parts of the hammer and trigger.
Thank you sir, solved the issue of dropping hammer on reset. Triger fixed: Geissele SSP.
Just goes to show that simply because you purchase a top tier trigger, doesn't mean it will work without some light tuning! THUMBS UP/LIKED VID :D
Im glad it helped!
Good video and explanation of the "distance" between the disconnect and the sear engagement to the trigger.
Thanks man! This really worked. I was careful when using the dremel and measured how much i started with. I removed about a millimeter of material.

Idk how mine passed quality control...Anyways, super informative vid. Learned how a binary trigger functions, AND how to fix it since I live and Iowa and binary triggers are illegal for civilian use here. But knowledge is power!! Thanks for the post, friend!!
Glad i could help.
You saved me a bunch of money. It only did the double fire when I slowly eased the trigger forward. Releasing the trigger quickly didnt cause the double fire.
Yes! This is exactly what mine did.
Hello all! Im glad this video has been as helpful as its obviously been to so many fellow gun enthusiasts! Id like some feed back on other stuff you guys would like to see. Just let me kno and id be happy to make a video.
You saved me a new trigger
Awesome, thanks for the info. .50 beowulf double fire scared the crap out of me. Easy fix
Short story is be very careful with trigger mods.
Free machine gun weeeeeeee.
In all seriousness, I left the sear spring out of my first AR on accident, free machine gun, but unpredictable af.
Thanks so much it worked! I was getting a double fire on the AR I am building but now it resets properly.
You stated exactly what I did.
Thank you , your video helped me fix my problem. I was going to buy a better trigger. Thanks again.
Thanks for this video. Couldn't find this info anywhere
In theory, if you removed the disconnector, would it be full auto?
Thanks for this video brother, took off a bit of the hammer 🔨 and a bit off the disconnecter and polish after and problem solved thanks a million!!!
Glad it helped brother
@@vbstangin just subbed brother
Thanks had the same prob. This fixed perfectly
Binary triggers are not illegal. ATF has not went against them. It's not a force resetting binary trigger like the WOT. Some states binary triggers are illegal tho
Something and everyone should also know if you do have problems such as this or any other kind of a problem that's causing your firearms not operate properly report it directly to the person or the manufacturer that you bought it from so that they have a record of it and can seek a solution. Also check to find out if there might be a recall on that particular problem or that particular part or firearm. Many times recalls are issued where you can send your firearm in to get it fixed for free or they will replace it for free.
Dude, Thanks a million! Awesome Video, helped a lot.
Bill Killgore you're welcome. Im glad i could help.
Forever modding
You saved me hundreds of $
Thanks for the video
Thank u for the Info very helpful
Someone reports you for shooting a double and it's not in a robbery or another crime. There must be a special place in Hell for that type of person.
Good video thanks for the help.
Great video! I just finished an AR15 pistol and it dbbl fired! Never happened before and I wasn’t sure it even did until I saw two shells! My bad -first by putting disconnected spring upside down 🤦🏻♂️… I fixed that but now I have a very slight 1/8” pull before trigger actually engages. My best description would be what it feels like when safety is on and you attempt to fire getting that little pull before safety stops you. Any idea what’s happening?
DUDEEE IT WORKED!!!!!!!!! Thank youuu soooo fucking much
Youre welcome man. Im glad it helped!
I replaced my disconnector
7:04 is WRONG. It is legal to shoot doubles, IF the 2nd "bang" comes ONLY when you let off the trigger, or make some OTHER action, after the trigger "pull". Just "triples" are illegal (which is unlikely to be even possible: the next type of trigger malfunction which lets off "more extreme than just turning it into a binary trigger" should be "unlimited" not "triples" unlimited meaning "full-auto"). ~Bill S Preston, ESQUIRE.
The Butcher Of Benghazi. Libya indicted me because I'm too stupid to delete my incriminating emails? You dont "gun" much huh. Triples are very possible. Do yourself a favor and quit spreading your "knowledge" until you fully understand.
I have a problem to were it will shoot once then the trigger won't reset just stay stuck in place even with the upper off should I just get a new trigger?
Thank you. My kit was t together correcty but it isn't ihtting the disconnector at all. I haven't shot it because I knew it was going to possibly shoot on its own. I was staring at it and playing with it and realized it was not matching like it should. Out od spec. So thank you. This is exactly what is wrong. You saved me a lot of hit and miss.
Thank you I am having this issue with a brand new 9mm rifle. I did swap out the springs for the JP3.5 springs which I have on three other ars and have not had this issue. Could those springs have anything to do with this issue.
Its not the cap, Its the degree of the step on the sear and the hammer! You need about a 20 degree step, That's what makes the trigger break and makes it feel lighter on pull! Polishing will always makes it feel better on the pull though! And you dont ever wanna use a dremel to do trigger work unless you are a pro! You sand paper and or a very light file! And Binary triggers are 100% legal! As long as its a trigger pull for 1 shot! Or as the say a motion of the trigger on pull and release!
Uh, many states do in fact allow binary triggers, plus those that have an NFA rifle with the three shot burst or full auto are also legal. You don't need an NFA registered rifle if you're using a binary trigger in many states just check your state laws to make sure that you're legal within your state.
Can you just purchase a new disk connector. and if so will the problem come back? And this eventually we're now naturally from where? And is this dangerous?
1:36, "extractor is NOT a disconnector". You say. is is a few times while showing your Dremel grinders. What's wrong here?
Hello. Thank you for this video. My trigger just started the occasional fire on the release 2 weeks ago. I forgot and went to the Range to try some new reloads.. My trigger is about 1 1/2 years old. I did some basic polishing when I found out about polishing A while back.
So far your video is still a good basic explanation in my search today. I will try this fix.
Thank you again.
O and instead of going thru all of this you can but a nice stainless Anderson firing group for 19 bucks and they are silky smooth
Would be better if you used proper terms for the parts. Its a disconnector vice an extractor. geez. Glad you corrected that later in.
My DPMS started double firing exactly like this after about 200 rounds. I have to release the trigger in a very quick exaggerated fashion to get a proper trigger reset and avoid double firing. Good info, I’ll try it out
first try. still got the hammer fall on release. Second try and I got no reset. guess I took off too much. it was just micrometers too. bummer.
You are a genius !
Thanks, pal. This exactly what I was looking for.
FINALLY
I have this happening on my SR556
Thank you for sharing this. It helps me fix the disconnector early disengaged.
Bro my trigger won’t pull at all with the safety or with out the the safety.... it looks like it’s this but I’m not sure....
IDK people pay good money for binary triggers. Free built in binary trigger sounds like a bargain.
Depends on where you are but binary is legal in some states and full auto is still legal if you have an 07 ffl and an 02 sot
Binary trigger shoots pull and release, and they are legal. Just sayin'. Good video.
Thank you, great explanation!!
Shoot on pull and release is legal by ATF definition, that is a binary trigger.
I’m having this problem even with a drop in after this happened
Thank you!!
My trigger when I put the pin in the trigger is hard and I know it’s the pin what do I do in this case?
Finally someone who knows! You're brilliant man thanks.
Thank you for this video it was driving me crazy I could not figure out what the problem was I appreciate it
Seems everyone (including myself) is having this problem with the AR trigger group. AK... never a problem.
How many AK's have you built? The biggest prob with the low end milspec triggers are that they are just that....low end. Also if youre building an 80% then youve got to understand that the trigger/hammer pin holes will not be exactly the same on every lower built, due to tolerance stacking between the hammer/trigger holes as well as tolerances with the FCG.
Thanks a great fix! Exact same thing with mine. Thanks for the video!
A+ all I could find online was people blaming an inverted disconnect spring, did this on a factory trigger that was out of spec.
Yes, me as well..it took me a minute to find this. And it works.
I know this is 6yrs old but bianary trigger are legal now lol
If double aren’t legal then how are binary triggers?
Binary triggers are not illegal. Bump Firing is not illegal.
Fixed my issue in 15 minutes. Thank you 👍
So grateful for this video, thank you!
Is it ok to use a Daytona tactical hammer on a psa trigger?
The military check after cleaning and re assembly should let you know if your AR is going to go full auto or double tap before you go to the range, I just cannot believe what I have seen on this video and so many have done something similar. The systems check is easy, empty gun, charge or cock the hammer, pull trigger on empty chamber, hold trigger down, charge again, let off on the trigger, it should reset, at this point it should work unless you have removed metal from the surface hardened parts of the hammer and trigger.
Ed Sanderson this procedure isnt 100% ... You obviously havent built many guns. Or fully understand how they operate or malfunction.
I love you I thought I fucked it up
thanks bro, that fxed my issue
Dremels and triggers are a bad combination.
Thank you 🙏🏾
Good video..! FUCK the range, I go shooting in the woods!
Wish I had anywhere like that. :-/ Texas has nothing but ranges, private land, and state or federal parks where no shooting is permitted.
You are a good man, sir. Because you care.
This happened on my RA 434 drop in
