These Scope Mounts made by Talley Manufacturing offer a unique and simplified one-piece scope ring and base solution for the Wilson Combat New Ultra Light Arms 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 industry's tightest tolerances.
