Ruger Mark III & Mark IV .22 LR 10-Round E-Nickel Magazine (2-Pack) - 90231 - UPC 736676902316

Product Description

The Ruger Mark III / Mark IV .22 LR 10-Round E-Nickel Magazine 2-Pack (90231) is an official factory OEM replacement accessory package manufactured by Sturm, Ruger & Co. Purpose-built for the famous Mark III and Mark IV rimfire handgun series, this 2-pack provides precision-machined feed geometry, effortless magazine drops, and unyielding mechanical reliability for target shooting, rimfire competition, and plinking range sessions.

Constructed from high-tensile steel and treated with a premium Electroless Nickel (E-Nickel) plating, these magazine bodies offer superior slickness, reduced friction, and exceptional corrosion resistance against moisture and carbon fouling. The ultra-smooth E-Nickel surface treatment ensures consistent feeding cycles while allowing spent or empty magazines to eject cleanly from the grip frame upon release.

Each magazine is equipped with a integrated side loading button and an internal heat-treated music wire spring, allowing rapid, finger-friendly manual loading of .22 Long Rifle cartridges. Featuring a durable polymer base pad and a precision-engineered follower, the Ruger 90231 E-Nickel 2-pack delivers exact factory fitment and smooth rimfire presentation shot after shot.

*Armorer Bench Notes & Real-World Staging Guidance:

Fitment Matrix: Direct fit for Ruger Mark III and Mark IV target and hunter series pistols chambered in .22 LR (including 22/45 models using standard Mark series steel bodies). Note: Will NOT fit original Ruger Standard, Mark I, or Mark II pistols without swapping base pad buttons.

1. Verify the firearm is completely safe, clear, and unloaded before testing or loading magazines.
2. Depress the magazine thumb button along the side slot to lower the follower easily while loading .22 LR cartridges.
3. Periodically wipe down the E-Nickel exterior and internal channel with a dry microfiber cloth to remove wax and lead residue from rimfire ammunition.
