SOLGW L89A Drive Lock M-LOK ARCA - AR-15 Handguard - 13.75" - Steel Barrel Nut

Precision-oriented AR-15 builds just got a purpose-built mounting solution — the SOLGW L89A Drive Lock Rail brings RRS-Lock compatible integrated ARCA functionality to what was already the most robust M-LOK handguard in the DriveLock lineup.

The SOLGW L89A is a free-float M-LOK AR-15 handguard with integrated ARCA rail designed for end-users who demand maximum mounting capability, precision platform compatibility, and field-proven structural integrity in a single handguard.

The L89A evolves the proven L89 platform with precision shooter feedback at its core:

Integrated ARCA with RRS-Lock compatibility: The full-length integrated ARCA rail gives precision shooters direct tripod mount attachment without adapters or add-on rails — and RRS-Lock compatibility ensures a secure, tool-free interface with high-end precision support systems.

Steel barrel nut for rigid, zero-movement lockup: The included steel barrel nut pairs with the Drivelock system to deliver an unyielding connection between handguard and upper receiver.

Integrated steel QD sockets and cable management: Two integral steel QD cups (limited rotation) provide dedicated sling attachment points, while fast slots beneath the 12 o'clock rail accommodate zip-tie cable routing — keeping your setup clean and snag-free under field conditions.

Anodized to match SOLGW receivers: The Mil-Spec MIL-A-8625F Type III hard anodize with NiAc seal and non-reflective finish is matched to SOLGW receivers, making the L89A the natural centerpiece of a complete Sons of Liberty Gun Works build.
