Can someone tell me if this doesn’t look right. Currently the bolt catch will not hold it back. It just slides forward. Can some one more experienced give me some insight. This is my first AR build. The angle seems to be off.
any help is appricated.
Thanks
That angle on the carrier is normal.
Can you manually lock the bolt to the rear, but it won’t hold back on the last round when fired? Or can you not even lock the bolt to the rear manually?
Ive yet to fire the weapon yet. It seems like when i go to lock it back with no mag in as soon as I pull the weight off the charging handle it loses it and slams forward,
Your bolt carrier looks fine. I’d suspect the bolt catch.
Stupid question but, are you depressing the bolt catch? Without a empty magazine in it won’t lock back by itself.
Are you saying what inks linger said or are you saying that with it locked back as soon as you pull the charging handle, the bolt catch falls down and the bolt slams foward?
the real question is how stupid is the answer!!!thinking this was my problem
OK just tried that as well, same thing seems to hold and as soon as the weight is off the charging handle that sucker slams forward
It sounds like either
a)your bolt catch/detent/spring has been incorrectly installed
b)your lower is out of spec.
Can you post some details on the rifle? What parts are used?
I hope my lower isnt out of spec. Its a Noveske however its a chainsaw
Noveske chainsaw lower
Vltor MUR-1A upper
BCM mod 4 handle
BCM bolt carrier group
CMMG LPK
BCM 6 position stock (mil spec)
Vltor H buffer and spring
Presuming the bolt catch came with the cmmg kit?
Yes

My experiences with CMMG were very poor and I would not recommend any of their products to anyone.
Awesome. Thought I was putting together somewhat of a quality build

Other than the LPK I think you did just fine.
Lol I appreciate that. The sad thing is I paid a sweet premium for that LPK too like $120
If you have another tried and true lower, switch the upper to it and see if you have the same problem.
Check this thread to see if this is your problem:
When you lock the bolt back manually, it can be released by pulling back on the charging handle.
There is nothing wrong with your build.
Show a picture of the lower and the bolt catch
this is what I was thinking too, unless he’s saying it is doing that with an empty magazine in it?
