Black Dirt Rifleworks

The Black Dirt Rifleworks™ E1 ultra-light weight slim-line free float handguard for the AR-15 features the M-Lok accessory mount system and is a complete re-imagination of what a solid, well designed and affordable free float handguard should be. Black Dirt Rifleworks™ design engineers wanted it to be tough enough for even the most extreme duty use / environments while remaining among the lightest weight available and they wanted it to be drop dead sexy. They delivered and in a big way!

Designed to be durable, slim and snag free Black Dirt Rifleworks™ departed from the traditional continuous top rail design used in most similarly featured handguards on the marked in favor of a split rail design with M-Lok accessory attachment points in between giving the shooter a modular light weight design with M-Lok accessory attachment points at the 12, 3, 6 & 9 o'clock positions. The extruded aerospace grade 7075-T6 aluminum alloy is precision machined on to exact design tolerances hard coat anodized to U.S. military specifications (Type III Class II) for durability in even the most extreme environments and scenarios.
