Available for the first time in this length as an exclusive release for Brownells, the M89 Handguard features SOLGW's revolutionary, patent-pending Drive Lock design. This innovative system uses three independent wedges that engage angular grooves in the proprietary barrel nut, clamping the rail with extreme force and precision while driving it rearward toward the upper receiver. The slightly larger inner diameter allows for more space around the gas block, enhanced rigidity compared to the M76, and slower heat buildup. SOLGW continues full production of the M76 while expanding the lineup with the M89.
