What You Get

This upper kit provides everything needed to convert a standard AR-15 lower receiver into a capable 17 WSM rifle. The 20-inch barrel strikes a balance between velocity and handling, while the precision upper receiver ensures consistent accuracy.

Practical Applications

The 17 WSM excels at varmint shooting, small game hunting, and target work where flat trajectory and minimal recoil are advantages. The modular design allows shooters to maintain multiple uppers on a single lower receiver, maximizing versatility.

Build Flexibility

If you already own an AR-15 lower receiver, this upper kit transforms it into a dedicated 17 WSM platform. The straightforward installation requires only basic armorer's tools and mechanical knowledge.
