Product Description The Mission First Tactical Tekko AR Free Float M-LOK Rail System (TMARFF13MRS) is a high-performance 13.5-inch handguard engineered to replace the plastic factory handguard on AR platform rifles. Built from lightweight yet rugged 6061 aluminum with a Type 3 hard coat anodized matte black finish, this free-float rail system delivers a rigid, reliable foundation for accessories and optics. The monolithic-style top rail eliminates the gap between the receiver and rail for a seamless sighting platform, while the patent pending mounting, indexing, and lock-up system ensures precise fitment and consistent performance. Compatible with most suppressor installations, this handguard is an ideal upgrade for shooters seeking modularity, durability, and a cleaner rifle build.
