Made in America, these Browning AB3 Scope Mounts made by Talley Manufacturing offer a unique and simplified one-piece integrated scope ring and base solution for Browning AB3 Bolt-Acton rifles. This simplified mounting system eliminates the possibility of an out of alignment interface or loose connection between the ring and base of traditional two-piece designs. Ultimately this provides more strength and durability than rival steel rings and bases, but with a lighter overall weight. Fully CNC machined from lightweight aircraft-grade aluminum to the industries tightest tolerances, this rigid scope mounting platform requires no lapping and is ready to go out of the box.
