Ruger BX 1 Magazine 22 LR 10 Rounds Fits Ruger 10 22 Polymer Black 90005 UPC 736676900053
Product Description
The Ruger® BX-1 10-Round Rotary Magazine (SKU: 90005 / UPC: 736676900053) stands as the gold standard in rimfire reliability, serving as the factory OEM feeding system for the iconic Ruger® 10/22® platform and companion .22 Long Rifle actions. Engineered to deliver match-grade consistency and dependable cycle rates across all semi-automatic and bolt-action hosts, the BX-1 guarantees flawless feeding without protruding past the belly of the stock, preserving optimal balance and classic rifle ergonomics.
Manufactured from high-density, impact-resistant composite polymer, the BX-1 housing withstands extreme weather conditions, repeated bench drops, and abrasive solvent exposure without degrading structural integrity. The internal assembly centers on a precision steel-reinforced rotor powered by a corrosion-resistant stainless steel torsion spring. Integrated steel feed lips maintain exact cartridge presentation angles and headspace interface, resisting the continuous battering of heavy-recoil high-velocity loads and preventing premature feed lip spreading common to all-plastic aftermarket alternatives.
Engineered for high-volume range training, small-game hunting, and rimfire competition, the BX-1's flush-mounting footprint eliminates field snagging on brush, shooting bags, and vehicle doors. Its proven rotary geometry isolates each .22 LR cartridge in its own individual radial fluting, preventing rim-lock and bullet tip distortion that frequently plague standard inline rimfire stick magazines. Whether you are running precision drills or plinking steel targets, the factory BX-1 delivers seamless feeding and long-term durability.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Engineered exclusively for Ruger® 10/22® Carbine, 10/22 Takedown®, 22 Charger™, SR-22®, Ruger American Rimfire® (.22 LR), Ruger Precision® Rimfire (.22 LR), and 77/22® (.22 LR). CRITICAL: Will NOT feed or seat in .22 WMR (.22 Magnum) or .17 HMR receivers due to cartridge length differential. Always load rimfire ammunition ensuring the rim of each succeeding cartridge sits forward of the prior cartridge rim as the rotor indexes. Never apply heavy petroleum-based oils or grease inside the rotary mechanism; use only dry film lubricants (PTFE) to avoid attracting carbon fouling and lead particulate.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Depress the magazine release latch on the trigger guard housing and verify that the empty magazine drops freely without hanging on stock sidewalls.
- Load ammunition by depressing the internal rotor counterclockwise with your thumb, seating up to ten (10) rounds of .22 LR brass sequentially into the steel feed throat.
- Insert the loaded BX-1 straight into the receiver magazine well until the spring-loaded forward retention plunger audibly clicks into positive lockup.
- Perform a tactile pull-check on the magazine baseplate, then cycle the bolt handle fully to verify positive chambering and extractor hook engagement.
