Vltor Clamp On Low Profile AR-15, LR-308 Gas Block

The Vltor Clamp On Low Profile AR-15 LR-308 Gas Block is a clamp-on gas block designed 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 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.
