Suppressor Ready Design
The XPERT SR is engineered as a true suppressor-ready platform. The 18-inch barrel is threaded from the factory, allowing shooters to easily attach a .22 WMR-rated suppressor. This feature significantly reduces muzzle blast and recoil, making the rifle more comfortable to shoot and ideal for backyard plinking, small game hunting, and training in noise-sensitive environments.
The Winchester XPERT SR .22 WMR combines increased power with modern suppressor-ready features in a compact and accurate bolt-action rifle.
.22 WMR – Increased Power and Performance
Chambered in .22 WMR (Winchester Magnum Rimfire), this rifle offers substantially more power than traditional .22 LR models. The .22 WMR delivers higher velocity and greater energy, making it an excellent choice for small game hunting, varmint control, and predator hunting at extended ranges. It provides a flatter trajectory and improved terminal performance while still offering low recoil and affordable ammunition options.
18-Inch Threaded Barrel
The XPERT SR is equipped with an 18-inch threaded barrel. This length provides an excellent balance between velocity and maneuverability. The longer barrel maximizes the ballistic potential of the .22 WMR cartridge while the threading allows for quick and secure suppressor attachment. The barrel is precision rifled for consistent accuracy across a variety of .22 WMR ammunition.
Shadow Synthetic Stock
This model features the modern Shadow synthetic stock. The stock offers a tactical-inspired design with a matte black finish and improved ergonomics. It provides a stable shooting platform with comfortable cheek weld and grip angles. The lightweight synthetic construction helps keep the overall weight of the rifle down while remaining extremely durable in field conditions.
Reliable Bolt-Action Operation
The XPERT SR utilizes a smooth and dependable bolt-action mechanism. The action is designed for consistent feeding, extraction, and ejection with a wide range of .22 WMR ammunition. This reliable operation makes the rifle suitable for both casual range use and serious small game or varmint hunting applications.
