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

Is the mag fully loaded?

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.

I tried that,it drops and catches on the receiver when I do that =/.....should I instal a different catch? Thanks!

Well I took it apart and looked,my last rifle was a DPMS,my mags wiggled around in the magwell and the mag release was soft and easy to push in,this spring is definitely stronger than my old one,could I cut a few coils out of it to loosen the tension so it's not so stiff feeling inserting a mag?mags go in easy without the spring in,other than this I'm impressed with the fit and finish of my BCM parts,thanks!
