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

The Guntec USA AR-15 Low Profile Gas Block (GT750SS) is a machined steel replacement or build component for AR-pattern rifles. Built from solid steel and finished in matte black, the low-profile silhouette keeps the gas system tucked under most free-float handguards for a clean sight radius and a snag-free top profile.

Engineered for barrels with a .750" diameter gas block journal, the GT750SS is secured by a three set-screw design that locks the block firmly to the barrel. A traditional low-profile gas block is the right choice for AR-15 builds where reliable cycling and a sleek handguard profile are the top priorities.

The gas block ships ready to install with the included Allen wrench and gas tube roll pin. Weighing approximately 1.8 oz, it adds minimal weight to the build while delivering the durability expected from a steel component. Made in the USA by Guntec USA.
