223/5.56, 15" length free float rail mount with partial Picatinny Top rail and M-LOK slot system. Steel barrel nut included. CNC machined from Quality aluminum. Super light weight, only 11.5oz with barrel nut. This barrel nut system does not require "timing" of the barrel nut.
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 and hex wrench.
