The Mission First Tactical Tekko KeyMod AR Carbine Rail (Mission First Tactical part no. TMARCKRS) is a drop-in replacement for the factory 7-inch carbine handguard on AR-15 platform rifles. Machined from 6061 aluminum and finished in black hard-coat anodizing by Mission First Tactical, it swaps in without gunsmithing or special tools, held in place by the existing delta ring and handguard cap. The KeyMod attachment system opens up secure mounting points across the handguard for vertical grips, lights, lasers, bipods, and other rail-mounted gear. It is a straightforward upgrade for shooters who want more accessory real estate on a carbine build.
