BCM or Daniel Defense

why are BS threads like this allowed to stay open but discussion on a technical subject cut off after a few replies?..

This is the first I’ve heard about any BCM gun not liking any certain ammo, where did you hear about this? Personally I’ve shot all sorts of shit through my BCM, both 5.56 & .223, and it cycles everything like a champ…mines just a stock 14.5" m4.

Agreed. The answers can be found with a little reading.

OP both rifles will serve you well. My preference is to BCM.
