Geissele Super Low Profile Gas Block 0.750" Black Nitride

The Geissele Super Gas Block Low Profile is a gas block for AR-15 rifles and LR-308 style barrels, designed to fit under most free-float handguards. It is precision investment cast from 17-4 precipitation hardening stainless steel, which gives it corrosion resistance and strength, and it carries a black nitride finish.

The block is intended for use with 223 Remington and 308 Winchester barrels. The included instructions describe the standard set screw installation and a Bombproof Installation method that uses an included 3/16 inch pin to lock the block in place on the barrel. The pin is intended to keep the block from sliding or twisting during operation.
