Hi,I built a complete BCM BFH 16" mid upper and was curious,my receiver feed ramps don't line up exactly with the barrel extension ramps,the index pin is all the way back and the extension shoulder appears to be flush with the receiver face,the extension ramps sits foward of the receiver ramps about the width of my finger nail,is this a problem? Thanks.
would need a picture to say for sure. when you say they don't line up, you mean rotation-ally or front to back?
Front to back,the barrel extension feedramps are just a hair foward of the receiver feedramps
no issue.Originally Posted by witchking777
Ok thanks,my mag release is sticking and the mags are hard to push in,it's a BCM costs lower,any thoughts?
Is the mag fully loaded?

It does it loaded or empty,mags are Gen 3 PMAGS
How tight is your mag catch?

It's tight enough that the catch threads are just about flush with the release button
Flush is what I usually shoot for. Maybe back it out a turn or two and see if it helps.
