Made in America, these Kimber 8400 Scope Mounts w/8-40 Screws made by Talley Manufacturing offer a unique and simplified one-piece scope ring and base solution for the Kimber 8400 Rifle. 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.
