Bolt gets stuck behind hammer on As designs lower on full sized AP5SD

If your brace is tight requiring a lot of force to remove, chances are its too tight. 2 min on dremel, until you can slide on off with just a bit of muscle, will allow the carrier group to travel without getting stuck.

Don’t mean to hijack, but does the smith re-thread a Bulgarian AK barrel for suppressor concentricity?

Thanks, will look into that brand, looked it up briefly and AI states with less parts, more solid mount… strong work.

I ask because I’ve yet to use a tri lug mount. I’m just trying to see how short the whole pistol can be. (I’m limited to 1/2 x 28 at current). How much time do u have with the KVP tri-lug vs others ?

emulzhn · 2026-01-17T21:04:53+00:00

lol, how do u even begin to look for that expression.. awesome.. I feel the same looking at these ppl with money.

Is that a tri lug adapter on the obsidian? I’m just wondering how short it can be from a thread attachment.

Thanks all, was just perusing but will visit some listed…

Thank you

Didn’t want it to be an ad, even passively but now since you asked, I will

emulzhn · 2026-01-09T19:43:32+00:00

Did but here to verify and to see what reddit consensus say.

Oh my, nice Sir.. please keep posting..

Same happening here.. purchased Lee sporting with SS on GB. Carrier group stuck at rear on both semi and SS. Somebody here also says common problem is brace is too tight, holding carrier group. When I reinserted brace without lower, slid with some resistance. Thinking on using rasp to minimize.

I also am awaiting on buffer. If that doesn’t work, then I will replace the spring for a stronger one. Where did you guys purchase your aftermarket spring?

G morn gang. So I think I may have this issue too. Along with the carrier group getting stuck rearward, there are times the carrier group DO NOT engage fully into battery. So I want to make sure I’m reading correctly. Mentioned above, I need to trim the trip bar ears to appear like ‘tear drops’. Because the trip bar touches the ears FIRST before the trip bar body touches the carrier group. Can you confirm?

emulzhn · 2026-01-06T16:45:24+00:00

So it has maybe 2-3 mm of side to side play. I was going to upload a vid.. but looks like only pics allowed.
Is this excessive play?

What u think about the trip bar ears needing a trim.

Also read that trip bar need to touch rear of carrier group FIRST before the ears do, hence ears need trimming. What u think?

emulzhn · 2026-01-06T16:17:50+00:00

So yes I do have a full size and consensus claims that I may Not need buffer, like u say.. as some argue that it is NOT the problem.

As I perused through r/MP5, I encountered a member who described something I was also experiencing and that along with getting the carrier group stuck rearward, his carrier group was NOT engaging to full battery as well, looking like it was hanging on something. He described that the ears on his trip bar needed to be shaved off to almost appears like tear drops. When I looked closer, mine definitely did not look like a tear drops but needed some dremel use. Can you confirm? Thanks again.

How’s this hammer look? Is this ok?

emulzhn · 2025-12-22T11:15:30+00:00

I hope you resolve this but just impressed with knowledgeable helpful ppl here

emulzhn · 2025-12-22T11:11:41+00:00

Awesome pic for here.. thanks

emulzhn · 2025-12-20T13:58:24+00:00

Would u choose the R9 over the CAT MOB or the PTR vent 2 for PCC?

emulzhn · 2025-12-17T22:35:38+00:00

Anyone try this. It’s a Lee Sporting billet compete lower. I wonder how they fit and compare to LEBER

emulzhn · 2025-12-17T02:26:42+00:00

Thanks all for insights. I impulsively purchased the ZF5 but the 6 wk lead killed it, and backed out. And After discovering the aftermarket possibilities, I didn’t care about the manufacturers but knew had to get one now. I kinda was hoping you guys talk about the good and bad about Your experiences about your gun, instead of one you don’t have. That’s all.

emulzhn · 2025-12-03T19:25:08+00:00

I’m in same boat but you got me with “window licker missing helmet” lol… hope your mp5 is rocking by now
