The Troy MRF is the strongest user-installed free-floating rail system in the world. Troy MRFs are available for all AR15 or M4 weapon systems equipped with the original factory barrel nut. The MRF’s patented mounting system reinforces the barrel nut with a sturdy clamp and anti-rotation alignment lugs. Troy MRF BattleRails provide an uninterrupted rail extension and hand guard aligned perfectly with the host weapon’s flat-top receiver.
