This Cooper Arms Model 21 Varmint is built for one thing—pure, surgical precision in the field. Designed as a dedicated varmint and predator rifle, this single-shot platform strips away everything unnecessary and focuses on shot placement perfection. Whether you're working prairie dogs at distance or dialing in on coyotes across open country, this rifle is a purpose-built tool for serious shooters.

Chambered in .223 Ackley Improved, you’re getting enhanced velocity, flatter trajectories, and improved case efficiency over standard .223 Remington. Paired with the 24" heavy stainless barrel, this setup delivers exceptional accuracy and thermal stability during extended shooting sessions. Expect tight groups, minimal recoil, and the kind of consistency that makes long-range varmint work almost unfair.

The Model 21 action is a precision-machined, single-shot bolt system known for its rigidity and repeatability. The push-feed design cycles cleanly while maintaining tight tolerances that contribute to its benchrest-level performance. The walnut varmint stock with its wide beavertail fore-end rides bags beautifully, while the checkered grip and palm swell lock the rifle into your hands for controlled shooting in any environment.

.223 Ackley Improved shines in the varmint world—high velocity, low recoil, and devastating terminal performance on small to medium predators. With proper loads, this rifle excels well past typical varmint distances while maintaining strong energy levels. It’s a cartridge that rewards precision shooters who demand more performance without stepping into heavier recoiling platforms.

Condition doesn’t get better than this—true New Old Stock, never fired, and still housed in its original factory box. The wood shows beautiful figure, the metal is pristine, and the rifle presents exactly as it left Cooper’s Montana facility. For the shooter, it’s a tack-driver waiting to be unleashed. For the collector, it’s a clean, untouched example of Cooper’s craftsmanship—either way, this one hits hard.
