CMMG Low Profile Gas Block .750 ID – AR-15 Platform

The CMMG Low Profile Gas Block is a precision-machined replacement component designed for AR-15 platform rifles with .750-inch diameter gas journals. This gas block meters propellant gas from the barrel into the gas tube, cycling the bolt carrier group. Shooters replace factory gas blocks to achieve a cleaner profile under free-float handguards, reduce weight, or upgrade to a more durable unit after high round counts.

Machined from steel with a black finish, this low-profile design sits flush under most free-float handguards without adding bulk. Installation requires removal of the existing gas block and gas tube, alignment of the gas port, and proper torquing of set screws—basic armorer skills are recommended. A properly installed gas block ensures reliable cycling and consistent function.
