Bcm upper review. The first is the MCMR-13 with MK2 receiver and BFH ELW barrel. It doesn't take much effort to find people complaining about rusty barrels, incorrectly drilled gas ports, bad machining on carriers, out of spec parts, things breaking, etc, etc. Our favorite complete AR-15 upper receiver picks for general purpose, short barrel, pinned, and lightweight builds. So if the BCM was not intentionally undersized, it would have been a perfect fit. BCM uppers are very durable and reliable, they're one of the few manufacturers that didn't cut production costs during covid and still strive to provide a great product. See if their Recce-16 AR-15 deserves it. I see people occasionally laud this upper receiver quite a bit, but non-mil spec geometry made me shy away from it. They're far from precision rifles but they're more than enough to take into the battlefield. You may have heard about this new upper receiver, as Larry Vickers has already talked about it, and another YouTube channel has shared their thoughts on it as well. While they may cost more than some other options, the improved performance, longevity, and peace of mind are generally considered to be well worth the price. ddb ryj q80 oeus2e mokpri zlsl ljnzpb vi bgb4x rfrbstd1
