The Troy Industries M14 BattleRail is compatible with all standard M1a/ M14 stocks. This three railed upper handguard assembly is constructed of 6061-T6 aircraft aluminum and finished in a Mil-Spec type 3 hard coat anodizing. The Battle Rail replaces the factory upper handguard and extends to the rear sight base creating a more stable optic mounting platform and area for mounting accessories on the right and left of the rifle. Troy Micro BattleSights are recommended for use with this BattleRail. Made in the USA, available in Black and Flat Dark Earth.
