The revolutionary, patent-pending Drivelock design, uses a Hodge Defense-designed extrusion with three independent wedges that interface with the angular grooves in a proprietary barrel nut. This system clamps the rail onto the steel barrel nut with extreme force and precision, while also driving the handguard rearward towards the upper receiver. The slightly larger ID of that extrusion gives more real estate around the gas block, even more rigidity than the M76, and takes longer to heat.

SOLGW is not discontinuing the M76. That will remain in full production. They are just adding the M89 to the lineup.

    Lucked out as well with the 15″ M89 to go with my East India Starter Kit! Drive lock is solid as f&$#!!!

    I have been trying to get my hands on the M76 for some time for two of my SOLGW builds. I lucked into a M89 and it is a good solid rail even at the 15” length. Now I just need to try and get my hands on a 13”.
