So my youngest decided to put together an AR15, and we are having some (anticipated) operating problems.
When we put the parts into the lower, I just had him use the whole buffer assembly from my 308AR carbine that was in the parts bin. Now it will cycle on first shot, strip next round in magazine, but only put a small indent on the primer (second round). The bolt seems to be all the way forward and locked in to battery, but I am thinking there is something wrong with the buffer weight and timing of the system.
Parts list:
PSA 16 " mid length upper w/bolt
Aero stripped lower
APF 308AR carbine buttstock/buffer assembly
mixed stuff for lower internals
Here is some more information to help or muddy the situation....his mid length upper works fine on my A2 rifle buffer lower, and my rifle length gas system works fine on his carbine lower.
I am leaning towards getting a correct AR15 carbine buffer weight and spring and running that in his mid length.....that should fix the problem?
Or am I missing something completely off of what I am looking at here?
