CRR Quad Rail

Completely redesigned, the new CRR Quad is as easy to install as it is aesthetically pleasing. The new barrel nut is very simple to install. You have 4 optional mounting locations on the barrel nut and some shims in the kit to help you time this correctly. As far as the looks, this new design blows our past rails out of the water. If you decide to go with our billet upper and lower receivers, this rail compliments them like fine wine with a piece of wagyu steak.
