"The genesis of modular free float rails has arrived. Building off the TRX Extreme design that revolutionized rail based hand guards; the Alpha Rail® utilizes a new low-profile locking mechanism, which offers unparalleled strength and stability. The Alpha Rail® disperses heat and runs cooler than other close to the barrel rail systems.With unlimited mounting options and greater heat dispersion, the Alpha Rail once again sets a new industry standard in modular free float rail design. Comes with three detachable rails and all mounting hardware. Troy Alpha Rail is machined from 6061-T6 hardened aircraft aluminum and finished in MIL-SPEC Type III Hard Coat Anodizing. Works with standard AR15/M16 barrel nut. Made in the U.S.A. Black. 15"". No barrel nut included. Note: Alpha rails do not work with the TRX barrel nut or wrench."
