Leapers Inc. UTG Pro M-LOK 13" AR15 Free Float Rail Handguard

The Leapers Inc. UTG Pro M-LOK 13" AR15 free float rail handguard gives you a modular, lightweight platform for building exactly the rifle you need. Designed and manufactured in the USA, this mid-length handguard uses true free-floating construction to eliminate contact with the barrel, a proven approach for shooters who want consistent accuracy without the weight penalty of a traditional quad-rail system. The slim profile keeps your setup nimble while the M-LOK mounting system provides 42 slots across 7 tracks—enough real estate to attach lights, lasers, grips, and other accessories precisely where you want them.

Built from 6061-T6 aircraft-grade aluminum and finished in matte black hard-coat anodize, this handguard is engineered to handle rough use. The octagonal profile with grooved surfaces delivers a secure, comfortable grip for fast transitions and extended shooting sessions. Integrated anti-rotation tabs lock the handguard to your upper receiver with zero play, while the scalloped edges on the 31-slot Picatinny top rail keep your mounted optics and accessories snag-free. Installation is straightforward—the package includes a barrel nut wrench, detailed instructions, and the tools you'll need to get running right out of the box.

This handguard fits standard mil-spec AR15 upper receivers with gas tubes and barrels up to 1" in diameter. It comes pre-loaded with two M-LOK accessories: an 8-slot Picatinny rail section for additional mounting flexibility and a QD sling swivel adaptor. Not compatible with piston-driven systems or oversize upper receivers. Whether you're building a precision rifle, a competition gun, or a home-defense AR, the UTG Pro M-LOK gives you the modularity and reliability to grow your setup as your needs evolve.
