Sean having a issue...pulled m17 out to run some rds. Got off 8 rds. 4 riot,4 hp68. No problem. We'll safety swith sticks can't move it. Drop magwell and trigger assembly. Put all back together and no fire air empty from bottle. After awhile I switch to modified stock reg from Hd24 reg and spring. Now at factory spring and modified factory reg works fine. Ho back HD24 set up. Air rushes outta bottle when fired. Tried hd24 spring modified reg and same issue. So now back yo stock spring and modified reg. Can't figure HD24 set up just empty bottle on fire
@@lesslethalfordummies Probably around 950 I just have to get off my lazy but and remove a shim from my SHP tank all my other tanks are between 750 & 800 I don't want to go super sonic with 1100 psi on my m17
Which parts in the assembly allow full auto? Im in the UK and my trigger assembly internals are exact same as yours, only difference is I have a couple of Phillips head screws externally on either side of the housing next to the selector switch, when I remove those it allows me to select full auto but still fires in semi 🤔
@@garethmccaig8674try this video? You can see the two pins sitting vertical behind the trigger in the cover photo. ua-cam.com/video/o-wDVYR2jZY/v-deo.htmlsi=jX736hD9GwJ3oOOM
Anything you heart desires really. A few washers are probably the easiest just dont want them to be sloppy or too big an outside diameter. Maybe a machine screw nut since they are low profile.
What is the size of the hex screw primarily used? I have the one that came with the marker that works but I need an exact same one to twist both sides off at the same time. Having a hard time finding the exact size It's a little larger than 3/32 and little smaller than 7/64 I believe
@@lesslethalfordummies thank you, i'm purchasing now. Was wondering if you knew if the one inside the handle of m17 that requires a long allen key to insert in deep is the 3mm or the 4mm to remove the handle?
There are no orings in the trigger group. Did you by chance recently do the prv delete? That is where you would find one of the smallest orings in the marker.
Yeah i x rayed your video and saw no ace for o ring. Its so small interior diameter of o ring sludes right over those chrome pins inside. That how small. Actually can not find a o ring that small anywhere on that marker. You the man...any ideas or maybe a foreign o ring from something else.
It could be something foreign maybe from factory assembly. The absolute smallest oring on the m17 is found inside the prv on the tip of the brass stem.
@@lesslethalfordummies yeah maybe...its a hair bigger than prv o ring..pretty close size as washers that connect reg to receiver with cotter pins Thx Sean as always you the man. Ty
Shawn, I'm resisting you m17 mods. I'm just up my output to 1000. So, is this mod needed? I do not plan on raising up to 1100. Thanks again for all your vids.
I downloaded all these vids to work on my marker thank you for making them
😀
Thanks for taking the time to make this shim sear mod video. Appreciate the effort!
You're welcome!
Thank you for taking the time to do this. Your video is easily the best one to follow along with
No problem thanks for watching.

You make it look easy! Thanks!!
It gets easier every time you do it. Just dont rush yourself.
Great video I'm kind of glad you made that goof it helps to see a rerun lol
Depending on the pressure you decide to run i have found this may not be necessary anymore.

@@smokingunclefrank6037 you would probably be okay at 900-950 and that would put you 45-50j range.

You probably need the two full auto pins. You can get them at HomeDefence-24 now.
@@lesslethalfordummies I’ve already bought them, I’m unsure where they go?

@@lesslethalfordummies when I compare my trigger assembly with yours from the video, I have all the same steel pins in the same position as you have
@garethmccaig8674 might be better to send me an email with a pic of your trigger group opened and i will see if i can spot whats wrong.
What other objects/ or size screw can I use to insert into the spring?
Thanks!

The m17 uses metric threaded fasteners. The two primary sizes are 3mm and 4mm. Hope that helps.

@@nickychan4022 that is a 4mm screw but unsure of length.

Ya been gone for a minute. If you see this have? Shim the sear but found a tiny...tiny o ring on mat. Can't figure where goes.

So long as your marker is functioning i would just toss the extra oring in the parts bin.
What is the point of this shim mod?? Is it necessary if you're doing the other mods to support the extra power?
Shim mod is necessary if you are running 1100psi. I havent needed anything yet running 800psi.

@jrhjrh9372 no, not if you are not having any malfunctions. First upgrade if any is bolt spring. The trigger group is t as important.
I did the regulator bypass and now my gun fires like a machine gun even when I press the trigger only once. Will this fix it?
The shim will not stop autofire. You need a better bolt spring or just reinstall the brass orfice
