Ruger SR-556 10-Round Magazine - Black

Ruger SR-556 Steel Mag

This is Ruger's own 10-round magazine for the SR-556 and AR-556 rifles, chambered in .223 Remington and 5.56 NATO. The short body sits low under the receiver, which keeps it clear of the bench or the ground when you shoot from a rest or prone. It suits owners who want a factory-matched spare, and shooters in places where magazine capacity is limited to ten rounds.

Features

• 10-Round Capacity — Holds ten cartridges in a compact body that is shorter than a standard 30-round magazine.
• .223 Rem / 5.56 NATO — Feeds both cartridges, the civilian .223 Remington and its military counterpart 5.56x45mm NATO.
• Blued Steel Body — The magazine tube is steel with a bluing treatment, a chemical finish that darkens the metal and helps it resist rust.
• Orange Polymer Follower — The follower, the platform that pushes each round up toward the chamber, is bright orange so you can see at a glance when the magazine is empty.
• Heat-Treated Steel Spring — The spring is made from heat-treated steel wire, which helps it hold its tension through repeated loading.
• Ribbed Body Panels — Pressed vertical ribs run down both sides of the steel body.
• Corrosion-Resistant Finish — The black finish is made to stand up to handling, sweat and damp range days.
• Factory Ruger Part — Made by Sturm, Ruger & Co. for its own SR-556 and AR-556 rifles.

Fit and Construction

Ruger lists this magazine for the SR-556 piston rifle and the AR-556, so owners of either can buy it knowing it matches the factory spec. The body is blued steel, which is heavier than polymer but holds its shape well. The orange follower and heat-treated spring are the same type of internals Ruger uses in its own rifle magazines.
