The Mission First Tactical Tekko Drop-In Quad Rail (brand part number TMARCIRS) installs on an AR carbine with a screwless, drop-in fit, held in place by the existing delta ring and handguard cap rather than added hardware. Four MIL-STD 1913 Picatinny rails run around the 7-inch aluminum body, giving a shooter a secure mounting platform on all four sides for lights, grips, and optics. A monolithic-style continuous top rail eliminates the gap between the receiver’s rail and the handguard’s rail, so a red dot or optic mount can span both without a seam. Mission First Tactical builds the whole unit from lightweight aluminum and finishes it in hard coat black anodizing for durability.
