Bowden Tactical J1355313 Cornerstone Handguard 13" M-LOK Made of Black Anodized Aluminum Includes Barrel Nut for AR-Platform

The Bowden Tactical J1355313 features a 1.3 inch internal diameter which can accommodate the majority of low-profile gas blocks, albeit there might be some interference with clamp-style low profile gas blocks. It is also equipped with MLok slots at the 3, 6, and 9 positions that are made in compliance with Magpul standards. This guarantees appropriate fit with any Magpul certified accessories. Each AR10 & AR15 Cornerstone handguard that we offer comes with a pre-heat treated, 2-inch long 4140 steel barrel nut. This ensures a sturdy and stable accessory mounting. The barrel nut has undergone nitriding, not phosphating. Each handguard comes with its respective mounting instructions and hardware.
