Sons of Liberty Gun Works L89 DriveLock Rail, 13.75″ MLOK

The L89 handguard takes what makes the M89 handguard a best in class product and elevates it even further.

Featuring a Titanium barrel nut, 7 sided M-LOK attachment slots, two integrated steel QD (limited rotation) sockets, and maximized cooling slots beneath the 12 o’clock rail, the L89 is built for end-users who require every little bit of mounting space they can get.

Built on the M89/Drivelock lockup system, the L89 incorporates valued end user feedback in getting the most utility possible out of a handguard in modern combative applications.

Maximum strength, maximum mounting space, and weight savings material choices make this one of the finest fighting handguards available to date.
