Description
The Winchester Xpert SR .17 WSM 8rd Threaded is a bolt-action precision rimfire rifle built for shooters who demand sub-MOA accuracy at the range or in the field.

The threaded muzzle (1/2×28) comes suppressor-ready, and the three-lever M.O.A. trigger system breaks clean and crisp.

Key Features
- Three-Lever M.O.A. Trigger System – Why it matters: Adjustable from 2.5 to 5 lbs, this trigger eliminates creep and overtravel, giving you a predictable break for tighter groups at 100+ yards.
- Button-Rifled Sporter Barrel with Target Crown – Why it matters: Consistent rifling and a protected crown maintain bullet stability and accuracy, even with high-velocity .17 WSM loads.
- Threaded Muzzle (1/2×28) with Protector – Why it matters: Mount a suppressor or compensator without smithing. The included protector keeps threads clean when not in use.
- 8-Round Rotary Magazine – Why it matters: Reliable feeding in a compact, low-profile package. The detachable design lets you reload fast without fumbling.
- Drilled and Tapped Receiver – Why it matters: Mount any standard rimfire scope base or rail directly. No gunsmith needed — just bolt on your optic and zero.
Who It’s For
This rifle is for the rimfire competitor who wants flat-shooting performance without stepping up to centerfire costs. It’s also ideal for varmint hunters who need precision at 200+ yards with minimal wind drift. If you run suppressed for noise discipline or recoil management, the threaded barrel is a must-have.
