The Gunwerks GRB actions are generating a lot of buzz in the custom rifle market. We offer stainless steel or titanium scope mounts finished to the highest possible standards, that will complement the accuracy and durability of your Gunwerks rifle.

We hold our mounts to tighter tolerances than allowed under the Picatinny standard (MIL-STD-1913), ensuring complete compatibility with all Picatinny style, as well as Weaver style scope rings.

They are availible in a natural, satin silver finish (bead blasted), or with an incredibly tough black finish called GunKote.
