The Troy MRF is the strongest user- installed free-floating rail system in the world. Troy MRFs are for all M16/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. This BattleRails provides an uninterrupted rail extension and hand guard aligned perfectly with the host weapon's flat-top receiver.
