Winchester XPR Extreme SR 450 Bushmaster 20" Rifle

Winchester XPR Extreme SR: Purpose-Built for Big Game

The Winchester XPR Extreme SR represents a serious commitment to field-proven rifle design. Chambered in 450 Bushmaster, this bolt-action rifle combines modern manufacturing with practical features that matter when hunting demanding game.

Barrel and Action

The barrel is spiral-fluted and button-rifled steel, finished in Flat Dark Earth Cerakote for corrosion resistance. At 20 inches, it balances velocity with maneuverability in thick cover. The threaded muzzle (11/16"-24) accepts suppressors, reducing recoil and report for a more pleasant shooting experience.

The machined solid steel receiver is the foundation of accuracy and longevity. The bolt features nickel Teflon coating for smooth operation and reliability in adverse conditions.

Trigger and Safety

The MOA Trigger System provides a clean, predictable break. The two-position thumb safety is intuitive and reliable. A recessed target crown protects the muzzle from damage while maintaining accuracy.

Stock and Ergonomics

The composite stock wears Mossy Oak Bottomland camouflage—proven in the field for blending into natural surroundings. Textured grip panels ensure secure handling even with wet or gloved hands. The Inflex 1 recoil pad manages the 450 Bushmaster's substantial kick.

Magazine and Capacity

A detachable box magazine system allows quick reloads and easy cleaning. The three-round capacity suits the deliberate pace of big-game hunting.

The Bottom Line

The XPR Extreme SR is built for hunters who demand reliability, accuracy, and weather resistance. It's a rifle designed to perform when conditions are worst and stakes are highest.
