NEW Professional Drill Jig for Mounting Optics Bases and Rails

Brownells has added a new Professional Drill Jig to its collection of gunsmithing tools. The $194.99 jig, made by B Square, aligns hole-spacing for popular scope bases on most popular military bolt action receivers. According to Brownells, this jig: “aligns mount hole-spacing for Weaver, Redfield and Buehler bases on all Springfields, U.S. Enfields (not SMLE), Japs, Mausers, Remington 30s and similar bolt actions.” Brownells says this unit saves time and eliminates tedious measuring as it “automatically locates holes in reference to recoil shoulder, and aligns and spaces holes vertically on the centerline of the receiver.”

Brownells’ Drill Jig features all-metal construction. The jig bars, base block and top piece are gold-anodized aluminum while the bore arbor and “V” bushings are blued steel. For the $194.99 price, the Pro Drill Jig includes two bars (Mauser and Spgfld/Enf/Jap,), complete mounting assembly, and an interchangeable No. 31 drill bushing.

Editor’s Comment: In the past, we haven’t been particularly impressed with B Square consumer products, particularly B Square rails and rings, but with CNC machining these days, the Professional Jig should be a quality tool.
