Sons of Liberty Gun Works M89 DriveLock Rail, 15″ MLOK

The Sons of Liberty Gun Works M89 M-LOK Handguard features their new DriveLock attachment system that keeps the free float handguard locked tight against the 4140 steel barrel nut.

This is the 15” version which is perfect for 16″ and longer barrels. The SOLGW M89 Handguard is machined from high quality aluminum and hardcoat anodized black. The full length picatinny top rail is great for mounting backup iron sights. Included is an M-LOK QD sling socket allowing you to position your sling however you want.
