Reptilia 10.5" M-LOK FDE Handguard for M4 Upper Receivers 100-357

The Reptilia 10.5" M-LOK Handguard is a high-performance, free-float rail system engineered for the AR15 platform and compatible with all M4-profile upper receivers. This handguard features Reptilia's patented turnbuckle mounting technology, which utilizes a reverse-threaded nut assembly to create high-tension pressure against a standard 1.25-inch barrel nut, ensuring a rock-solid, anti-rotational lockup without the need for traditional anti-rotation pins or tabs. Machined from aerospace-grade 7075-T6 billet aluminum, it offers seven sides of M-LOK mounting slots and a full-length Picatinny top rail with angled front cuts to improve access to muzzle devices or suppressors. The slim, snag-free profile is finished with a durable MIL-STD Type III hardcoat anodizing in Flat Dark Earth for superior corrosion and wear resistance.
