Anyone have these issues with this build?

Basically the bolt takes the round and doesn't close the whole way. It has gotten better since it was new but i figured after 200 rounds it would be good to go.

I run it wet and it will cycle 1-5 rounds in the mag... anymore than that...cycling issues.

Really doesn't like PMAGS or DPMS Mags....CProducts mags are better.

Any suggestions? Polish the ramps? anything?

I really want this thing to feed 10 rounds no prob.

Are you using the correct buffer and spring?

Have not had that issue before.
