Frequently Asked Questions
What barrel journal diameter does this gas block fit?
This gas block fits barrels with a .750-inch diameter gas block seat — the most common diameter for standard carbine and government-profile AR-15 barrels. Always measure your barrel’s gas journal before ordering.
How does this low-profile gas block attach to the barrel?
The BCM low-profile gas block uses set screws to secure to the barrel. Best results are achieved on properly dimpled barrels. Apply blue thread-locking compound to the set screws during installation for a secure hold.
Is a low-profile gas block required for a free-float handguard?
Yes. Free-float handguards route over the gas block and require a low-profile design to fit within the handguard’s inner diameter. A standard-height gas block with a front sight tower will not fit under most free-float handguard designs.
