Sons of Liberty Gun Works M89HA ARCA - AR-10 Handguard - 13" - Cosmetic Blem

Bring precision-shooting utility to your large-frame AR-10 without compromising fighting-rifle rigidity. The Sons of Liberty Gun Works M89HA combines the battle-tested M89H Drive Lock platform with an integrated full-length ARCA rail, giving SR25/DPMS High Shelf builds a seamless interface for tripods, shooting rests, and support system accessories.

The Sons of Liberty Gun Works M89HA is a heavy free-float handguard for SR25/DPMS High Shelf AR-10 rifles that integrates a full-length ARCA rail at the 6 o'clock position alongside the Drive Lock attachment system.

Four features make this the go-to for precision-oriented AR-10 builds. The Drive Lock titanium barrel nut provides the same proven, repeatable lockup as the M89H series. Full-length M-LOK slots at 3, 6, and 9 o'clock deliver maximum accessory mounting flexibility, complementing the ARCA rail rather than competing with it. Two integrated steel QD sockets with limited rotation support fast sling transitions. Fast Slots beneath the top rail keep cable runs clean and unobtrusive.

Fits SR25/DPMS High Shelf pattern AR-10 upper receivers. Note: requires either a compatible upper or drilling an anti-rotation pin hole slightly smaller than SOLGW AR-15 spec.

Type III hard anodized per MIL-A-8625F, Class 2 with NiAc seal, non-reflective finish. Anodized to match SOLGW receivers. Engraved T-Marks standard.

Designed for precision rifle competition, designated marksman builds, and field shooting applications requiring rapid tripod or support system transitions.

Includes M89HA rail, titanium barrel nut, barrel nut wrench, and lock-up components. Sold as a cosmetic blemish — minor aesthetic imperfections may be present; structural integrity and full functionality are guaranteed.
