RFI: BCM 11.5” GTG?

Thanks for your indulgence; a search brings up much detritus. If I can grab a BCM 11 AR pistol w/SBA3 brace, any reason not to?
TIA.

I have one and like it. Use it with a Cherry Bomb, Omega and Plan B.

My BCM 11.5” ELW fluted is my favorite upper. It works great suppressed or unsuppressed.

My experience, pretty much anything BCM is GTG.

My son has one and runs it hard without any issues.

Rock solid, love mine.

Perfect, thanks, gents. I’ll see what I can do.

I love BCM but they sound like they may not be the most balanced on gas. From what I’ve seen and heard (no personal experience) they have produced 11.5 carbine barrels with gas ports anywhere from .073 to .076. The former is likely a good balance but the latter is probably overgassed. I have no doubts that it’ll still work but personally I’d prefer it on the smaller end. I don’t know if these are normal variances (doubt it) or they went from one to the other over time and if so, whether they opened it up or shrink it down. I do know that several people have asked and BCM refuses to answer.

The 3 11.5 BCMs I have experience with are not overgassed.

Work rifle is a BCM 11.5” standard barrel upper/BCG on a 3 pin Commando lower. Runs great, no issues, although rate of fire is slightly higher than the 20-25k round Colt 933 upper it replaced.
