Product Description The Mission First Tactical Tekko Metal AR Carbine M-LOK Rail System is a durable, lightweight upgrade that replaces the factory plastic AR-15/M4 carbine handguard in minutes. Designed for fast drop-in, screwless installation, it requires no gunsmithing and no special tools, and it does not require permanent modifications to your rifle. The rail system is retained by the delta ring and handguard cap, while the M-LOK interface provides a secure, modular mounting platform for compatible accessories such as Picatinny rail sections, vertical grips, lights, lasers, bipods, and other rail-mounted equipment.
