Does the BCM MCMR-13 handguard fit 12.5-inch BCM barrels?

[Henry Pointe]

I bought the BCM 12.5" complete upper receiver group (from Bravo Company USA) and was wondering if their MCMR-13 handguard fits this barrel. Would the handguard protrude out past the barrel?

BCM® MCMR-13 (M-LOK® Compatible* Modular Rail)

BCM's free-float 13inch MLOK handguard eliminates loads from barrel for more accurate shooting. Designed for carbine or mid-length ARs.

Yes It will stick out over the barrel. 10 inch MCMR would be good.

Yes. As a general rule of thumb, one inch under the length of barrel will allow an MD to be installed/removed with the handguard in place. In this case 11.5". There options will work but the handguard must be installed after the MD and removed to allow access to the MD.

For reference, this is the handguard in question with a 14.5" barrel...

Depends what you're going for, they gave ya perfect info though! Some also intentionally have a longer handguard, typically suppressor or linear comp setups. Have one myself, compensator is only 1/2" out the end of handguard.

Yeah, it gets annoying that everybody seems to jump from 10 straight to 12.5-13 on rails.

For a 12.5 barrel you need an 11.5 -11.75" handguard. I used a Geissele mk16 13.5 that I milled down to 11.75 and it fits perfectly to a can.

My ideal would be the midsize DD RIS-II GL/SSC, but they only made 125 of them, and the front-sight pocket version possibly only one or two prototypes.

If it's a kino setup with an fsb then you can get an m4 ris and have chopboss mill it to fit. He does rail shortening and milling for unique setups.

You're asking if a handguard that's longer than the barrel will stick out past the barrel.....
