Our Assessment: This Cooper Arms Model 21 Mannlicher Carbine in .223 Remington is a distinctive and high-quality single-shot bolt-action rifle with a more refined sporting configuration than the typical varmint-pattern Cooper. Dating from the 1990s–2000s, it features a compact 19″ barrel, blued finish, full-length Mannlicher-style walnut stock, and a drilled-and-tapped receiver fitted with Leupold bases and 1″ rings with inserts. The lack of iron sights indicates it was intended for scoped use, and the .223 Remington chambering makes it well suited for light varmint hunting, target work, and precision shooting with mild recoil.

The bore condition is excellent, described as bright with sharp rifling, no erosion, and only light fouling, rating 9.75/10 in the writer’s opinion. Mechanically, the action functions correctly, though the rifle has not been test fired. The metal condition is also very strong, with approximately 98% of the original blued finish remaining and only light scratches and handling marks noted. The screw heads are sharp, the markings are clear, and the rifle’s overall metal presentation supports its Excellent condition rating.

The Mannlicher-style checkered walnut stock is a major visual and collector feature of this rifle. It has a capped forend, capped semi-pistol grip, straight comb with shadowline cheekpiece, and checkered steel buttplate, giving the rifle a classic European-inspired sporting profile. The stock shows light handling wear with scattered light scratches and compression dents, but there are no chips or cracks, and it remains in Excellent condition overall. While no box is included, the Leupold scope rings add practical value, and the rifle’s excellent bore, high original finish retention, and uncommon Mannlicher configuration make it a particularly appealing Cooper Model 21 example.
