Vltor Clamp On Low Profile AR-15, LR-308 0.750 SS

The Vltor Low-Profile Gas Block is small enough to fit inside most rail systems. This gas block is an excellent replacement for the archaic fixed sight tower gas block, which has been the standard since the early 1960s. The Vltor Low-Profile Gas Block covers one-inch of the barrel surface and is made to the tightest tolerances. Manufactured from 17-4 PH stainless steel and available in matte black oxide finish or blasted to give a matte gray finish. All models are made to fit barrels with a 0.750 inch gas block diameter. Clamp-on design for AR-15 and LR-308.
