Bowden Tactical J1355313 Cornerstone 13in M-LOK AR Handguard Barrel Nut

The Bowden Tactical J1355313 Cornerstone Handguard 13" M-LOK provides American-made quality at import-like prices with a precision-extruded 6061 T-6 aluminum construction and a durable black hard coat anodize, designed for AR-15 platforms and featuring a 1.3 inch inner diameter to accommodate most low-profile gas blocks while noting occasional interference with clamp-on styles; this 13" option delivers a slim 1.5 inch overall width and a featherweight profile that enhances handling without sacrificing rigidity, thanks to the pre-heat treated 2 inch length 4140 steel barrel nut that is nitrided for added durability and rock-solid mounting, and it ships with mounting instructions and hardware for straightforward installation. The Cornerstone handguard is offered in Full Flat Top or Competition Top configurations and includes MAGPUL-standard MLok slots at the 3, 6, and 9 positions to ensure compatibility with a wide range of accessories, enabling precise accessory placement and quick customization for hunting, target shooting, or tactical training. With American sourcing, these rails bring reliable, corrosion-resistant performance to your AR-15 build, backed by a 100% warranty against manufacturing defects.
