The Reptilia Handguard in 9.4-inch M-LOK FDE (Reptilia part no. 100-331) is a free-float AR-15 rail sized for carbine-length builds that want full M-LOK accessory mounting without extra weight, finished in FDE for a color-matched rifle. Reptilia builds its handguards to the same standard the company applies across its grip and stock lines: purpose-shaped, no wasted material, and finished for durability under hard use. At 9.4 inches, it covers a common mid-length gas system footprint while leaving room to run a compensator or suppressor beyond the muzzle. It installs on a standard AR-15 upper using a compatible barrel nut.
