Ruger 90361 BX 25 22 LR 25 Round Detachable Magazine Black UPC 736676903610
Product Description
The Ruger® Genuine Factory BX-25® Magazine (SKU: 90361 / UPC: 736676903610) is the gold-standard 25-round detachable rimfire magazine engineered by Sturm, Ruger & Co. for the Ruger® 10/22®, 22 Charger™, Ruger American® Rimfire, Ruger Precision® Rimfire, and 77/22® platforms chambered in .22 LR. Designed to deliver the same renowned feeding reliability as the factory 10-round BX-1® rotary magazine, the BX-25® eliminates high-capacity rimfire feeding bottlenecks during high-volume range sessions, rimfire steel challenge matches, and small-game hunting.
Constructed from an impact-resistant, glass-filled matte black polymer clamshell body, the BX-25® features precision-cast stainless steel feed lips permanently integrated into the magazine tower to maintain exact cartridge presentation geometry over tens of thousands of cycles. Internally, a high-tensile stainless steel constant-force spring drives a smooth, self-lubricating polymer follower along an optimized curved track, preventing rim-lock and nose-diving even with bulk-pack lead round-nose or high-velocity copper-plated .22 LR loads.
Unlike sealed aftermarket magazines that trap waxy rimfire bullet lube and unburned powder residue, the BX-25® is assembled with three hex-head steel machine screws—allowing complete, rapid disassembly on the workbench for thorough solvent cleaning and internal maintenance. Its textured exterior ribbing ensures a positive purchase during rapid reloads from mag pouches or cold, wet hands in the field.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Genuine OEM fit for all .22 LR rotary-magazine-pattern Ruger firearms, including the Ruger® 10/22® Carbine/Takedown/Target, SR-22® Rifle, 22 Charger™ Pistol, Ruger American® Rimfire, Ruger Precision® Rimfire, and 77/22®. CRITICAL WARNING: Will NOT fit the Ruger® SR22® handgun (pistol), 10/22® Magnum (.22 WMR), or .17 HMR rifles. When loading .22 LR cartridges, push each round straight down and slide rearward so the rim sits cleanly in front of the round below it—never allow rims to overlap (rim-lock). During routine cleaning, torque the three clamshell housing screws to 8–10 in-lbs; over-torquing can pinch the polymer body and restrict follower travel.
- Ensure the host firearm is completely clear, bolt locked open, and chamber visually and physically verified empty before inserting or testing any magazine.
- Inspect the stainless steel feed lips and internal follower path for excess shipping oil or debris; wipe clean with a dry lint-free cloth (run the interior dry, as wet lubricants attract rimfire powder fouling).
- Load up to twenty-five (25) .22 LR cartridges one at a time by depressing the follower and sliding each rim cleanly under the stainless steel feed lips without overlapping rims.
- With the bolt open, insert the BX-25® straight upward into the receiver magazine well until the rear magazine latch clicks positively into engagement, then tug downward to confirm lockup.
- Release the bolt to strip and chamber the top round, verify smooth cycling, and disassemble periodically via the three hex screws every 1,000–1,500 rounds to clear waxy rimfire residue.
