Ruger American Rifle 4 Round 308 Multi Caliber Short Action Rotary Magazine Matte Black SKU 90689 UPC 736676906895
Product Description
The Ruger® American Rifle Short Action 4-Round Rotary Magazine (SKU: 90689 / UPC: 736676906895) is a factory original OEM feeding solution engineered specifically for Ruger American bolt-action rifles. Purpose-built to restore factory feeding reliability or serve as an essential field backup, this multi-caliber short-action magazine secures flush into the rifle's underside, maintaining a streamlined, snag-free profile across rugged stalking and blind hunting environments.
Constructed from high-density, impact-modified composite polymer, the housing exhibits exceptional dimensional stability under extreme mechanical stress and thermal variance. Internally, a precision-wound music-wire spring powers a smooth rotary wheel mechanism that drives cartridges along dedicated feed tracks without tip-deformation or rim binding. The self-lubricating polymer surface provides extreme resistance to harsh field moisture, CLP solvents, mud, and abrasive debris, preventing common feeding hangs experienced with degraded aftermarket units.
Designed for rapid, intuitive manipulation, the magazine incorporates an integrated front locking lug and positive rear retention catch that seats into the stock bottom metal with an unmistakable audible click. The flush exterior preserves natural balance at the rifle balance point when carrying one-handed, eliminating snag points against brush, bipod straps, or tree-stand rails while cycling short-action cartridges flawlessly.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Compatible with Ruger American Rifle and Predator models chambered in .308 Winchester, 6.5 Creedmoor, 6mm Creedmoor, .243 Winchester, and 7mm-08 Remington using standard factory flush-fit bottom metal. CRITICAL: Will NOT seat into or feed Ruger American models configured for AICS-pattern (AI-Style) detachables, Stanag/AR-15 magwells, long-action receivers, or Ruger Precision Rifles. Never use aerosol bore cleaners directly on polymer feed lips.
- Ensure the host rifle is completely clear, point the muzzle in a safe direction, open the bolt fully rearward, and physically inspect the chamber and magwell.
- Depress the magazine latch at the front of the factory magwell and extract the spent magazine downward out of the receiver.
- Load up to 4 rounds into the rotary feed channel by pressing each cartridge downward and rotating it rearward under the retaining lips, confirming the case head seats against the rear wall.
- Angle the rear locating interface of the magazine into the stock cavity, then drive the front upward until the retention latch snaps into full mechanical lockup.
- Cycle the bolt handle forward and downward to verify smooth cartridge pickup, extraction, and clean rotary follower indexing into the chamber.
