The Troy TRX Extreme is the lightest, sleekest and strongest modular free float rail system available. The TRX Extreme Battlerail features an uninterrupted top rail and proprietary rotary locking system utilizing Troy's proprietary barrel nut for a secure and solid mounting platform. The TRX Extreme is significantly lighter than standard quad rails due to the lack of side and bottom rails. The modular design allows for specific placement of smaller rail segments only where the operator needs them. The result is a extremely strong, lightweight, slim and versatile free float modular mounting platform. The free float design increases accuracy by assuring that there is no barrel movement when interacting with the rail. The TRX Extreme Rifle rails for M16, M4, and AR15 type Carbines are manufactured and sold by Troy Industries in the United States.
