Key Features
- Threaded, Button-Rifled 16.5″ Barrel — The button-rifling process creates consistent grooves for sub-MOA accuracy, and the threaded muzzle (1/2×28 TPI) allows quick attachment of suppressors or muzzle brakes. Why it matters: You get match-grade precision without needing a custom barrel.
- Three-Lever Adjustable Rimfire M.O.A. Trigger — Adjust pull weight from 2.5 to 5 lbs via three levers, no tools required. Why it matters: Dial in the exact break point for competition or field use, reducing trigger jerk and improving shot placement.
- Carbon Gray Perma-Cote Finish — A baked-on coating that resists corrosion, scratches, and UV damage. Why it matters: Holds up in humid environments, rain, and rough handling without rust or finish wear.
- Drilled and Tapped for Optics — Receiver comes pre-drilled for standard scope bases, ready for mounting a red dot or magnified optic. Why it matters: No gunsmith needed—mount your preferred sight system in minutes.
- 10-Round Rotary Magazine + 10/22-Pattern Compatibility — Ships with one rotary 10-round mag; accepts aftermarket 10/22-pattern magazines for higher capacity or extended options. Why it matters: Gives you the flexibility to run standard 10-rounders or 25-round sticks for training drills.

FAQ
What is the twist rate on the Winchester Xpert SR 21 Sharp barrel?
Per Winchester specs, the barrel has a 1:16″ twist rate, optimized for 21 Sharp ammunition. This twist stabilizes standard 40-grain loads and lighter projectiles typically used in rimfire training.
Does the Winchester Xpert SR accept Ruger 10/22 magazines?
Yes. The rifle ships with a single 10-round rotary magazine, but it is designed to accept aftermarket 10/22-pattern magazines. Note that some aftermarket magazines may require minor fitting to the magazine well, per Winchester’s compatibility notes.
What type of scope rail does the receiver use?
The receiver is drilled and tapped for standard #6-48 screws, compatible with most rimfire scope bases (e.g., Weaver, Picatinny, or dovetail adapters). No rail is included; you will need to purchase a base separately.
Can I adjust the trigger without removing the stock?
The three-lever adjustment system requires removing the barreled action from the stock to access the levers. Once set, the trigger will hold zero. This is a one-time setup step for most users.
Is the Winchester Xpert SR California-compliant?
This model is not listed as California-compliant. Check your local regulations before ordering. We ship to all 50 states, but compliance is the buyer’s responsibility.
