The Mission First Tactical T-MARC is a drop-in, screwless installation that does not require any alterations to the rifle. It is held in place by the Delta ring and a handguard cap. The four MIL-STD 1913 Picatinny rails provide a secure platform for mounting a variety of accessories from vertical grips, lights, lasers and bipods. Its monolithic construction eliminates any gaps commonly found between the receiver and the rail.
