COLLECTIBLE FIREARMS

Atlas Collectible Firearms is profoundly honored to present a Holy Grail, handmade masterpiece of American custom rifle building: a rare FULL FACTORY CUSTOM BUILT Cooper Arms Model 57M Custom Deluxe bolt-action sporting rifle chambered in the flat-shooting .17 HMR caliber. Bearing the super low serial number 2946 stamped sharply on the receiver, this top-tier custom rifle features a 24-inch tapered octagonal barrel with a deep high-polish blued finish, an ebony forend tip, and an exquisite factory Turnbull bone charcoal case-hardened receiver, trigger guard, box-magazine baseplate, and matching case-hardened Talley scope rings. Representing the absolute pinnacle of early "Stevensville, Montana" Cooper Arms hand-crafted perfection, this ultra-rare, museum-tier rifle stands as an irreplaceable crown jewel for any advanced rimfire collector.
Stocked in a spectacular piece of exhibition-grade, highly marbled European walnut, this rifle features a classic capped pistol grip configuration with a swept right-hand shadowline cheekpiece, an ebony grip cap, sling swivel studs, and a checkered steel buttplate measuring a 13-3/4" length of pull. The hand-cut checkering is executed in a multi-panel layout accented by elegant arrowhead intrusions and uncheckered ribbons. This outstanding custom rifle package includes one original factory magazine fitted with a matching case-hardened baseplate and the factory case-hardened Talley scope rings mounted to the receiver.
The overall cosmetic condition of this rare Cooper Model 57M remains in very fine, near-mint condition throughout, appearing virtually new with only a few minor handling marks across all factory finishes. The exhibition-grade European walnut stock is near perfect at 99%+, showing only a couple of minor, superficial handling impressions in the wood finish. Mechanically, the bolt action functions with hand-fitted, glassy smoothness, locking up crisp and tight, while the 24-inch octagonal barrel preserves a mirror-bright, pristine bore with sharp, razor-defined rifling lines throughout.
