The Ncstar NCSTAR M-LOK HANDGRD/CARB EXT BLK is a drop-in AR-15/M4 Carbine Length handguard designed to replace standard Carbine and M4 length handguards, extending past the handguard cap to fit around the front sight post and bayonet lug for a truly integrated profile. This extended handguard places the top Picatinny rail at receiver height, forming a seamless continuous top rail that runs over the Delta Ring, while seven angled rows of M-LOK slots offer versatile mounting options for accessories along the length of the handguard. Solidly constructed with an anodized black finish, it ensures a durable, secure fit on AR rifles, maintaining compatibility and rigidity when mounting optics, grips, and a wide array of accessories. The package includes two accessory M-LOK to Picatinny rail sections, a short (5-slot) and a medium (9-slot) rail, which can be positioned in any of the seven M-LOK rows to tailor rail space to your preferred setup. This M-LOK Extended Handguard combines practical length, modular capability, and a clean, factory-height top rail to enhance control and accuracy in dynamic shooting scenarios.
