The EGW Browning AB3 SA 1-piece Picatinny base gives you a solid, one-piece foundation for mounting optics on your Browning AB3 rifle. Built in the USA and designed for shooters running zero MOA—ideal if you're working within typical hunting distances up to 500 yards—this base integrates directly into your receiver with a clean, compact profile. The ambidextrous beveled design works equally well for left and right-handed shooters, and the full-length Picatinny rail gives you flexibility in ring placement and accessory mounting without forcing you to abandon factory iron sights.
EGW machines these mounts in-house and finishes them with tumbling, sandblasting, and Type II anodizing to handle field use and weather. The center channel running the length of the base reduces unnecessary weight while maintaining rigidity—a practical touch for hunters who cover ground. Installation is straightforward: EGW specifies 20 inch-lbs of torque and a small amount of blue Loctite (sold separately) on the mounting screws, and they include a wrench for the job.
Before you order, measure the hole spacing in your AB3 receiver and confirm it matches EGW's published dimensions; receiver variations can affect fitment. Everything in the box—mount, screws, wrench, and packaging—is made in the USA. If you're planning shots beyond 500 yards, EGW also offers 20 MOA bases; this zero MOA version is the choice for standard hunting-distance setups.

Frequently Asked Questions
Does this mount work with my Browning AB3?
Yes—this base is designed for the Browning AB3 SA. However, EGW strongly recommends measuring the hole spacing in your specific receiver and comparing it to their published dimensions before purchase, as receiver variations can occur.
What's the difference between zero and 20 MOA bases?
The zero MOA base is designed for shooting at standard hunting distances up to about 500 yards. If you plan to shoot at longer ranges (500–1000 yards), EGW offers a 20 MOA base, which provides additional elevation adjustment. When using a 20 MOA mount, EGW recommends zeroing your rifle at 200 yards.
Will this mount interfere with my factory iron sights?
In most cases, the center channel design allows factory iron sights to remain usable, though this can vary depending on your specific rifle setup. If iron sight co-witness is critical to your setup, verify compatibility before purchasing.
What tools and materials do I need to install it?
The mount comes with a wrench for the mounting screws. EGW recommends applying blue Loctite (sold separately) to the fasteners and torquing them to 20 inch-lbs. No other special tools are required.
