Sons of Liberty Gun Works L89A Free Float AR-15 Handguard - ARCA / M-LOK 13.75"

The SOLGW L89A Drivelock ARCA Handguard delivers a free float M-LOK rail with an integrated Arca interface for shooters who need tripod-ready mounting alongside accessory space. Built on the same Drivelock lockup system as the standard L89, this AR-15 rail delivers direct tripod attachment without adapters.

• Full-length integrated Arca rail with RRS-Lock compatibility
• Seven-sided M-LOK attachment slots
• Two integrated steel QD sockets, limited rotation
• Drivelock barrel nut system for rigid, repeatable lockup
• Fast slots beneath the top rail for zip-tie cable routing
• Mil-Spec Type III hard anodized, NiAc-sealed finish

The L89A's full-length integrated Arca rail runs along the handguard's bottom, giving precision shooters a continuous mounting track for Arca-equipped tripods, bipods, and shooting bags without clamping adapters. RRS-Lock compatibility allows rapid positioning along the rail while engaging a secure lock, removing the usual trade-off between adjustment speed and stability. The Drivelock barrel nut system gives the handguard a rigid, repeatable connection to the upper receiver, keeping mounted lasers from losing zero under hard use. Seven-sided M-LOK slots provide accessory attachment at every cardinal and diagonal position, two integrated steel QD sockets give shooters a dependable sling attachment point, and fast slots beneath the top rail accommodate zip-tie cable management. This 13.75" length is designed for standard mil-spec AR-15 upper receivers. This length ships with a steel barrel nut for a rigid, zero-movement connection to the upper receiver.

Sons of Liberty Gun Works builds components to the standard demanded by professional end-users, with a focus on combative application, material integrity, and field-proven design. This handguard carries the SOLGW Limited Lifetime Warranty.
