The Mesa Tactical Sureshell Saddle Rail Mount is a lightweight high strength mount for the Remington shotguns. Available with either a 5" or 20" Picatinny optic rail, and with 4, 6 or 8-round carrying capacity. The Mesa Tactical Saddle Rail is designed as an aluminum bracket that wraps around the top of the shotgun receiver. Factory Remington trigger pins are replaced by internally thread steel pins, to which both sides of the saddle rail are securely bolted. SureShell Saddle Rails feature a MIL-STD-1913 Picatinny sight rail along the top and a SureShell shotshell carrier on the left side of the receiver.
