CMC drop in trigger

[unicom]

I need to know if there is a way to adjust the cmc drop in. I took it to the range today and after about ten or so rounds the gun wouldn't load the next round. When I would pull the charging handle it was run to pull past where the hammer is to load a round I took it apart and the bcg moves fine inside the upper. Place the upper back on the lower and it gets rough buy the hammer. Any thoughts on how to fix this issue

I have a CMC drop in and haven't had any issues.

Maybe call them. They would probably know more about it.

Will call them sometime tomorrow

Never had a problem with the CMC triggers I installed.

Perhaps an installation issue?

It very we could be an install issue on my part. I will find out later the afternoon after work

could be any number of issues. is this the first time you have tried this trigger? what type of lower do you have? How is the fit with the upper/lower? Type of BCG? is there any play in the trigger group in the lower?
are you even sure this is a trigger issue? Does your function check work? Finally, not sure if you got autocorrected but I don't really understand your explanation of the problem.

Here is were I feal stupid. I didn't put the drop in trigger in this ar. I dont remember which ar its in. But there is still an issue with the bcg moving back after firing and not completely loading the next round or it slides on top of the next round part way jamming partially open.

It is short stroking. The BCG isn't moving back far enough to grab the next round.

Could be dirty/ dry, weak ammo, or a pile of other reasons.

Are you sure it is short stroking, or could this be a mag problem? Have you tried different mags?

 

[Dawico]

What ammo are you shooting and what modifications have you made to it?

Undergassed or too heavy of a buffer...

Gas block misaligned or gas tube blocked....

Loose gas block screws.
Had that happen before. Same symptoms.

 

[orbitup]

AKs are way less complicated.

I'm leaning towards gas block issue. It worked flawless t he first time s shot multiple mas gs through it and when I took it to Dietz gun range. Using same ammo and mags.

Turns out it just didn't like the one type of ammo I was using that day.
