Specifications:

• A true free float rail, which connects only at the Steel barrel nut. Since the rail doesn’t touch the barrel, shooting accuracy is improved in comparison with two-piece rails, when used with grips/bipods that can flex the Steel barrel.
• Includes steel barrel nut, screws, (2) shim rings for barrel nut timing, (2) 3 slot M-LOK rail segments, (2) 7 slot M-LOK rail segments and M-LOK screw set.
