A UTG .750" AR15 micro gas block in matte black is a direct impingement component built for shooters who want a low-profile setup under modern free float handguards. Made from precision-machined steel, this Leapers gas block is sized specifically for barrels with a .750" diameter at the gas port—a common spec on modern AR15s. If you're running a lightweight build, a competition rifle, or any setup where you need the gas block to stay out of sight, this compact design delivers without compromise.

The matte black finish blends with standard AR furniture and resists glare on the range or in the field. Because it's engineered to fit under most free float tubes, you maintain clean lines and maximize your handguard real estate for rails, accessories, or a slick fore-end. Installation pairs with standard direct impingement gas tubes—no exotic plumbing required.

UTG components are built on tight tolerances, and this gas block is no exception. Precision machining ensures a solid fit at the gas port and reliable cycling once it's in place. Whether you're assembling an upper from scratch, upgrading an existing rifle, or swapping out an oversized block that fouls your rail setup, this micro design solves the clearance problem without sacrificing function.
