I love everything about the AR-15 system in all caliber....
This community is so much better off with people like you In it. Keep up the good work!
Wow, that really hits me right in the feelers. Really...thank you! Comments like yours make this "job" all the more worthwhile. -Randy
"Direct impingement" IS a piston system. The piston is the rear of the bolt. The cylinder is the inside of the bolt carrier. It's just not out front where others are located. As far as "it $#!+s where it eats", you can shoot far more than 500-600 rounds before it gets dirty enough to have functioning problems, and even then, a few drops of oil will fix that. Certainly you will have a chance to clean the rifle in that time. You don't even need to to a complete cleaning. Just brush the chamber and lugs, and do a quick cleaning and lube of the bolt carrier group, wipe out the inside of the upper receiver. The problems I've seen shooters have are ones who "run her dry like they do in the sandbox". Well, here in the USA is not "the sandbox". Oil it. And you can't "over oil" the M16/M4/AR-15. Excess oil will blow out of the ejection port in just a few rounds. If problems, turn the rifle on its left side, drip in some oil through the ejection port... even motor oil dripped off a dip stick will do... work the charging handle a few times, and go back to the job at hand. A lot of guys use Mobile One synthetic 0w20 or 5w20 with good results.
Wtf was that!? I didn't do that. But good statements. Agreed.
Some people have been there and have the t shirt….while others are 50 mile experts…
This series has been super helpful. I would put these on par with Lucky Gunner's videos in terms of clarity and quality, and that's a complement!
Wow, thank you for that! It's rewarding to know that these are helping someone. -Randy
I wish they were in a playlist. Super well done, entertaining and informative. I'm new to the AR platform and I learned quite a bit so far.
Late to the game on answering this one... You wanted this Playlist? ua-cam.com/play/PLvexlTF9ttDqpICeC3Um-QCj1fkSUXEEc.html
Excellent narration. Voice tone and inflection excellent; highly professional presentation. Great job.
Thank you kindly, glad you liked it!
@@At3tacticalwhats ur favorite ar brands
@@Brandon_obs_ls Well, we are kinda partial to the AT3 brand and Spoiler Alert: We will be providing all components necessary to build a full, Made In USA, AT3 AR15 in the next month or so.
I love mid length the best imo over carbine
Wat a tease! I listened to you yammering on about stuff I already knew, anticipating the gas block alignment "tools and tricks" which never materialized.
Haha! This series is FAR from over. I'm sure we got you covered in some upcoming short FAQ style videos!
What I find strange, but probably isn't strange at all, is how similar the mechanics of direct impingement ARs are to old school stacked tube blow back paintball "markers". And, how similar the triggers are in each.
I like your red dots with the built in laser!!!
Randy! My favorite reefer!!
And now .... favorite "guntuber?"😂
Thanks you, my good Sir.
That's a nice armorers kit.
I enjoy this series. The information is well presented, and at a general level for those of us new to AR building. No doubt there are a lot more "fine tuning" to create your own personal perfect build.
Thanks! Definitely the next chapter for this series is a the next level of deep dive and offshoots. :)
Guessing sine 3d Filament would help with this alignment
I am continuing to enjoy this series of videos. Great explanations and examples. So far these videos have been very well produced. 👍🏼👍🏼
Thank you very much!
dang. this was an incredibly helpful instruction video. I'm new to firearm ownership, so these videos do a ton for knowledge building.
Awesome! Glad to help. :)
Big follower of BRS and always loved your work Randy. Now a huge fan of your work here. Keep it up and thanks for all the knowledge!
Awesome, thank you! Just can't stop sharing information, I'm addicted. Haha! -Randy
Very good info on this video.Xcellant class.
Glad you enjoyed it!
"without gas we wouldn't be talking today" lmao
I mean ... 🤣
I have heard of direct impingement referred to as internal piston. I kind of like that term better. It it just sounds better.
They are two separate gas systems..The AR is an internal piston and the MAS 49-56 is a direct impingement gas system..
This was insanely helpful!
Awesome! So glad to help.
Could you link the other video on the key please.
Hey Dave, are you looking for the BCG video about the gas key? If so, that's this link here. ua-cam.com/video/fmhcs34rYSg/v-deo.html
@@At3tactical I had already found it but ty tho....
It not a direct impingement gas system, this is a common misconception. It’s more like a reverse piston system. There are only like two rifles that are a direct impingement system used in the French MAS40-49. Just look up Forgotten Weapons- How does it work: Direct gas impingement on you tube.
Good info on the gas system, Randy. While choosing the gas block to match the mfg's recommendation as well as gas tube length is solid advice, one thing I wish you'd gone into depth about is choosing a barrel for the "desired" GT length. I specifically chose a mid-length 16" barrel for the extended dwell time. While carbine length will work fine on 16" barrels, the mid-length slows the BCG just a bit, which reduces the sharpness of felt impulse. Some folks might never notice the difference, but I can. Just thinking out loud here...
Absolutely on point and Thank You! There's definitely a lot more to this story to cover and I assure you, we'll dive pretty deep into these topics as the channel grows. (I believe I put a future video idea placeholder on the calendar just for testing this concept. Can you really measure recoil impulse with changes to dwell time...and if so, by how much do they fluctuate?) ;) -Randy
@@At3tactical Thanks for the reply, Randy! I truly enjoy your informative videos, and look forward to the rest of this series!!!
Slincer with mid length 9inch
Please do an AK series!!!!
Ohhhhh... You might be on to something there!
I'm currently trying to build my very first ar10. The question I have is, are ar15 and ar10(DPMS LR308) gas blocks the same? Some say yes, some say no. I just want to be sure as I'm new to building.
The important thing to pay attention to here is the gas block diameter and the diameter of your barrel. Most "standard" AR15 barrels use a 0.75" gas block. The diameter can increase as you go with thicker barrels like HBar or Bull barrels. Now comes your AR10 (.308) style rifles. You certainly can find AR10 barrels in a variety of thicknesses, but honestly it's likely going to be one of three diameters; 0.750", 0.875", or 0.936". Meaning.....drum roll.... they are the same when you think about it from the proper perspective, diameter! Good thing is almost ALL barrel manufactures will list this important measurement in the description, so there should be no guesswork.
Hope that helps!
@@At3tactical Thank you that clarifies my doubts! I had ordered a Ballistc Advantage .750 barrel and was unsure of gas blocks. But now knowing if I stick with the matched gas block journal size it should be just fine. Thank you again for the clarification!
The AR is an internal piston, not a true direct impingement..
Wait! This isn't BRS:tv. Buddy, where's the reef tanks? You do guns too?
Just the guns these days! Glad to have you aboard!
Mine is overgassed.. weak forward ejection and I have no idea how to install an adjustable gas block
Here is a place to start ua-cam.com/video/9dae4n0fFxY/v-deo.html
@@At3tactical will check it out
Holy hell, hold it like a man
🤣 Good 'Ol pistol braces! 🤣
This isn't even close to everything I wanted to know.
You know what? You're 100% right! That is not an accurate description at all. Got it updated to something more fitting, BUT...we will circle back to this topic and cover it more in depth down the road. Thank you for calling us out and keeping us sharp!
@@At3tactical Right on. I may recommend, grabbing a license to one of the finely detailed animations of AR-15 operation. Splice those into the descriptions of parts and operation, especially those which are internal. Reference "How an AR-15 works" youtuber Matt Rittman, and "M16 and AR-15 - How firearms work! (Animation)" youtuber Thomas Schwenke.
