CZ USA OEM Factory Rimfire Magazine - .22 Long Rifle, 10-Round Capacity - High-Impact Structural Polymer, Anti-Friction Follower - Fits CZ 452, 453, 455, 457, & 512 - Black - 12004
Product Description
Setting up a classic rimfire bolt-action rifle, organizing a small-game hunting kit, or tuning a precision rimfire trainer on your workbench reveals an immediate operational bottleneck: standard 5-round flush factory magazines that require constant, repetitive interruption to top off. Standard low-capacity lines force marksmen to break their physical cheek weld and reset their natural point of aim too quickly during intensive range practice or dynamic target tracking sessions. The **CZ USA™ OEM Factory 10-Round .22 LR Magazine (12004)** completely flatlines this reload interruption. It doubles your active shot tracking pool while maintaining the seamless, friction-free feeding properties expected of factory-original Czech engineering straight from your staging bench.
Precision-molded in the Czech Republic from CZ’s proprietary, state-of-the-art **high-impact structural polymer composite**, the unibody frame shell exhibits incredible geometric stability and core longevity. Unlike retro metal housings that are prone to denting, binding, or rust spotting over time, this advanced polymer matrix actively absorbs mechanical shocks from accidental bench drops. The lightweight material completely shrugs off hand sweat, damp trail moisture, and aggressive armorer cleaning solvents. The interior channel geometry is meticulously optimized to guide the volatile, rimmed profiles of standard .22 Long Rifle cartridges cleanly into line, preventing the staggering or interlocking rim jams that often plague aftermarket rimfire magazines.
In high-speed competitive rimfire precision matches, youth training courses, or field harvesting frames, the internal tracking physics of the **806703120041** blueprint provide an immense mechanical advantage. The housing features a low-friction, injection-molded **black no-tilt polymer follower** driven by a custom-wound, high-tensile stainless steel coil spring. This combination ensures flat, uniform vertical lifting pressure up to the final cartridge, allowing the rifle's bolt to feed rounds smoothly without bullet nose-diving anomalies. Complete with a compact, low-profile floorplate that mirrors the factory stock profile, this original equipment manufacturer (OEM) part locks cleanly into your rifle's magwell with absolute solid-state authority.
*Armorer Bench Notes & Technical Field Operational Guidance: The CZ USA 12004 magazine arrives fully completed and factory-sealed inside its protective plastic retail blister clamshell pack on your workbench. EXTENSIVE CROSS-MODEL RIFLE COMPATIBILITY MATRIX: This factory-original rimfire module features a universal interface architecture. It is engineered natively to fit **all standard CZ .22 LR bolt-action and semi-automatic rifle platforms**, including the legendary CZ 452 ZKM, CZ 453, CZ 455, CZ 457 series, and the CZ 512 semi-automatic tracking layout. It will *not* fit older CZ 451 models or large-bore rimfire actions chambered in .22 WMR or .17 HMR due to distinct cartridge length guidelines. **Bench Loading & Maintenance Sequence:** Because .22 LR ammunition utilizes exposed lead bullets or delicate wax coatings, push each cartridge straight down and slide it backward beneath the feed lips on your bench. Avoid forcing bullet tips against the front polymer wall to preserve your projectile geometry. **Pro-Tip Deep Cleaning Parameter:** To clean after high-volume sessions with dirty rimfire powders, slide a thin tool into the floorplate retention hole and slide the base pad off forward. Remove the spring and follower, wipe the inner guide channels completely dry with a clean cloth micro-swab, and reassemble. Never introduce wet lubricating oils or grease coatings inside the internal shell tracking lanes, as wet films collect greasy lead shaving dust and bullet wax paste, causing friction slowdowns downrange.*
Key Features
- Factory-Original OEM Certainty: Genuine CZ factory-engineered part guarantees flawless feeding, perfect spring return speed, and unmatched out-of-the-box cycling reliability.
