Ultra-low profile gas blocks are the ideal companion for any AR-15 barrel with a .750 diameter gas shoulder. Made from high-strength steel, these gas blocks are industry standard for all rifle builds using .750 diameter.
Perfect for any rail system, these ultra-low profile gas blocks are the ideal companion for any barrels with a .750 diameter gas shoulder. Made from high-strength steel, these gas blocks have a black oxide finish and match most black barrels perfectly. The block is drilled through the middle of the profile. The gas block clamps on to the barrel using 2 allen keys on the bottom of the block. Classic Firearms highly recommends the use of Loc-Tite or similar thread-locking compounds. Gas blocks will get very hot, so pick a compound according to your intended use of the firearm.
