Pacific Tool and Gauge has been making match grade reamers in the Pacific Northwest for decades. They've translated that same painstaking attention to detail and tight tolerances to their B-52 line of actions . We offer stainless steel or titanium scope mounts finished to the highest possible standards, that will complement the accuracy and durability of your PTG B-52 action.

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 available in a natural, satin silver finish (bead blasted), or with an incredibly tough black finish called Cerakote.

** Each base ships with #6-48 alloy steel Torx screws, and a T15 Torx wrench. Larger, #8-40 screws available upon request.
