Frequently Asked Questions

What barrel journal diameter does this gas block fit?

This gas block fits barrels with a .625-inch diameter gas block seat, found on lightweight pencil-profile and thinner carbine-profile AR-15 barrels. Measure your barrel’s gas journal diameter before ordering.

How does this low-profile gas block attach to the barrel?

The BCM low-profile gas block uses set screws for barrel attachment. Properly dimpled barrels provide the best holding power. Apply blue thread-locking compound to the set screws and torque to spec during installation.

Is a low-profile gas block required for a free-float handguard?

Yes. Free-float handguards require a low-profile gas block to clear the handguard’s inner diameter. A standard-height gas block with a front sight tower will not fit under most free-float handguard designs.
