What is the SONS OF LIBERTY GUN WORKS - M89 11.5" Drive Lock Rail Black?
Available for the first time in this length, exclusive release for Brownells.


The revolutionary, patent pending Drive lock design, uses three independent wedges that interface with the angular grooves in our 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 us 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.

Works well
Quick and easy installation. Didnt come with instructions which is annoying but they can be found online. Comes with wrench and as long as you have a torque wrench it is about as easy as a build as it gets. Looks great and I like the 45 degree mlok slots as well. Came with an aluminum qd sling attachment as well. Overall I'd recommend.
