The EGW Browning A-Bolt LA 1-Piece Picatinny Base in 0 MOA is a solid-steel scope mount engineered for hunters and shooters running the Browning A-Bolt Long Action. This rigid, one-piece design eliminates the flex and shift problems that plague two-piece bases, giving you a stable platform for repeatable accuracy. The full-length Picatinny rail accepts standard Picatinny or Weaver scope rings, so you're not locked into a single ring brand—pick what works for your rifle and your optics.
The 0 MOA configuration is your choice for shooting distances up to roughly 500 yards; if you're pushing past that distance, EGW offers a 20 MOA variant that shifts your sight line to optimize your elevation dial and scope adjustment range. The mount features ambidextrous bevels on both sides and comes completely finished in Type III anodized coating, which resists corrosion and wear in the field. Installation is straightforward: EGW specifies 20 inch-pounds of torque and a drop of blue Loctite (sold separately), plus includes the mounting screws and wrench. Everything—base, fasteners, packaging—is manufactured in the USA.
Critical compatibility note: this mount is designed for the standard Browning A-Bolt with #6 receiver screws. If you own a Browning AB3 (which uses #8 screws), this is not the correct base; EGW manufactures separate AB3-compatible models. Before ordering, verify your rifle's screw diameter and confirm hole spacing matches EGW's published dimensions for your receiver.

Frequently Asked Questions
Will this mount fit my Browning AB3?
No. This mount is designed for the standard Browning A-Bolt with #6 receiver screws. The AB3 uses #8 screws and requires a different EGW base. EGW manufactures AB3-compatible mounts under separate part numbers (43400 for 0 MOA, 43402 for 20 MOA).
What's the difference between 0 MOA and 20 MOA, and which do I need?
The 0 MOA base is ideal for shooting out to approximately 500 yards. If your hunting or shooting involves distances beyond 500 yards, the 20 MOA variant shifts your sight picture higher, giving you more elevation adjustment range on your scope dial. EGW recommends zeroing a 20 MOA mount at 200 yards.
Can I use this with any scope rings?
Yes, as long as they follow Picatinny or Weaver specs. The full-length Picatinny rail gives you flexibility to position your rings and accessories where they work best for your setup.
What's included, and what do I need to install this?
The package includes the one-piece base, mounting screws, and an installation wrench. You'll also need blue Loctite (sold separately) and a torque wrench to tighten to 20 inch-pounds. Before installing, measure your receiver's hole spacing and verify it matches EGW's published dimensions for the A-Bolt.
