Ballistic Advantage Low-Profile Gas Block Features The Ballistic Advantage Low-Profile Gas Block is machined to fit a .625 inch barrel gas journal giving AR-15 builders a precise reliable component for regulating gas flow to the system. Its low-profile design is built to clear most free-float handguards which keeps installation simple and avoids interference issues common with taller gas block designs. A Melonite finish provides corrosion resistance and a smooth low-friction surface that holds up to heat cycling from repeated firing. This combination of fit and finish reflects Ballistic Advantage s focus on parts that perform reliably under hard use. Finished in Black to match most AR-15 barrel and handguard finishes the gas block integrates cleanly into a build without standing out. A roll pin is required for installation but is not included so builders should have one on hand before starting the swap. Made in the USA the gas block is part of Ballistic Advantage s broader lineup of AR parts and barrels built to exceed the demands of serious shooters. The Ballistic Advantage Low-Profile Gas Block is a dependable upgrade for AR-15 builds for sale at GrabAGun.
