These Remington 700 20MOA Scope Mounts made by Talley Manufacturing offer a unique and simplified one-piece scope ring and base solution for Remington 700 rifles, to include models 721-722-725 and 40X. Mounts to receiver with 6-48" Length Screws. 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.
