The Troy TRX-308 BattleRail is built off the revolutionary TRX Extreme and brings the same sleek, lightweight, low-profile design to the more powerful .308 platform. A proprietary barrel nut provides superior strength. Includes handguard, barrel nut and three quick-attach rails. Not compatible with RRA LAR-8 or Armalite AR-10. Machined from 6061-T6 hardened aircraft aluminum and finished in MIL-SPEC Type III hard coat.
IMPORTANT: DPMS, BUSHMASTER and REMINGTON rifles have two different height upper receivers. Determine which receiver you have before purchasing:
The new "Low Profile" upper receiver has a 1/8" wide top portion where the charging handle is installed.
The older "High Profile" upper receiver has a 3/16" wide top portion where the charging handle is installed.
