EVOLUTION GUN WORKS Browning A-Bolt Long Action 0 MOA Picatinny Rail Scope Mount (43100)

Please check your screw diameter. Regular Browning A-Bolts come with #6 screws.
This product is designed for the standard A-Bolt, and A-Bolt 2 not the AB3. We do offer a mount for the AB3.
Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories.
The channel in the center reduces the overall mass of the mount, weighing in at 2-3oz on average.
Also, in many cases, it will not obstruct usage of factory iron sights. EGW’s one piece scope mounts are the obvious choice for hunters and tactical shooters alike.
This mount is a Picatinny-style base and compatible with Picatinny or Weaver scope rings.
Add EGW’s Practical or HD Scope Rings to make it a complete overhaul!
EGW machines these in their shop using one of the USA-made Fadal machining centers. After machining, the mounts are tumbled, sand blasted, and Type II anodized for long lasting durability.
The entire mount and accessories (from the mounting screws and wrench down to the packaging) are made in the USA.

Installation:
EGW recommends 20 inch lbs of torque and a drip of blue loctite (loctite is sold separately).
