Angstadt Arms
The Angstadt Arms Ultra Light 10" M-LOK aluminum handguard is a skeletonized free-float system built for shooters who demand minimum weight without compromising modularity. At just 7.7 ounces, this black anodized handguard sheds unnecessary material through aggressive lightening cuts while maintaining structural rigidity—a smart choice for AR-15 builds where every ounce counts, whether you're running a precision rifle, a lightweight hunting build, or a compact tactical setup. The free-float design isolates the barrel from handguard harmonics, supporting consistent accuracy across calibers.
Installation is refreshingly straightforward: no timing required, just a standard wrench. The M-LOK mounting interface is positioned at 3, 6, 9, and 12 o'clock positions, giving you full 360-degree accessory mounting flexibility. A continuous mil-spec Picatinny rail runs across the top, also featuring lightening cuts to keep weight minimal. Four QD swivel attachment points let you quickly rig slings or other gear without added bulk. The handguard's engineering includes a forward bore that expands to 1.405" for the last ¾", allowing most aftermarket suppressors 1.39" in diameter or smaller to tuck inside when paired with a 10.5" barrel—useful if you're building a compact or integrally suppressed setup.
Machined from 6061-T6 aluminum and finished in mil-spec hard coat black anodize, this handguard is compatible with both forged and billet upper receivers and works with all AR calibers except .308. The engraved Angstadt Arms logo marks it as quality hardware built by folks who understand the platform. Hardware is included, so you're ready to mount and go.
