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.
Note: Alpha rails do not work with the TRX barrel nut or wrench.
** Troy upgraded the TRX Extreme to the Alpha Rail. The TRX Extreme rail will no longer be available for purchase. **
Use dropdown menu to add a UTG 1.25" QD sling swivel for the 4" rail or the Troy SSQD mount.
