The AR15 tool key for the extension nut from Rock River Arms makes sense for every AR15 and AR10 owner.

It's not a must, but it's also not a big investment to properly equip your AR15 toolbox.

In 1996, brothers Mark and Chuck Larson founded "Rock River Arms" in a small shop in Cleveland, Illinois. Mark and Chuck brought over 40 years of diverse experience in the firearms manufacturing industry to their new venture. Rock River Arms quickly earned a reputation as one of the best manufacturers of hand-assembled custom 1911 pistols, and their NM frames and slides set new industry standards for tight tolerances, fit, and finish. The brothers soon applied their manufacturing know-how and attention to detail to producing custom rifles in .223 caliber in the "AR" style. Their initial focus on tighter tolerances and improving the fit, finish, and reliability of their rifles paid off when the Rock River Arms NM A2 rifle quickly gained popularity among high-performance shooters. The quality and reliability of Rock River Arms firearms continue to win new admirers.
