Guntec USA AR-15 Low Profile Gas Block .750 Stainless Steel

The Guntec USA Low Profile Gas Block is a precision-engineered replacement gas block designed for AR-15 pattern rifles. Machined from stainless steel with a brushed matte finish, this .750" diameter block installs on barrels with a matching .750" gas block journal, giving builders a clean, low-mass solution for free-float handguard setups and standard gas system upgrades alike.

The low profile design helps minimize interference with handguards and other accessories, and a three set screw clamping arrangement locks the block securely to the barrel journal. The short, compact footprint keeps overall weight down while delivering consistent gas flow to the rifle's operating system.

Built for AR-15, M16, M4, and M4A1 pattern barrels with a .750" gas journal, the stainless steel construction offers excellent corrosion resistance for long service life on the range or in the field.
