Triple-K
The Triple-K Remington 511/513 22 Long Rifle 5-round steel magazine is a reliable replacement or spare mag for owners of classic Remington rimfire target and sporter rifles. If you shoot a Remington 511, 513, 521, or Nylon 11 in .22 LR, this steel-bodied mag delivers dependable feed and retention for range sessions, small-game hunting, or casual plinking. Triple-K magazines are built tough to handle the demands of both vintage and modern rifle platforms, and this 5-round capacity keeps things light and handy for shooters who prefer a compact setup.
These rifles have a storied history—the 511 debuted in 1939 as a lightweight sporter, the 513 arrived in 1940 in both sporter and target ("Matchmaster") variants, and the 521 earned a name as a nimble junior target rifle. Many of these rifles are still in active use today, and finding quality aftermarket magazines can be a challenge. Triple-K specializes in hard-to-find mags for discontinued and legacy firearms, so this 5-rounder is a solid choice if your magazine supply has worn out or been lost over the years.
The steel construction resists denting and delivers consistent feeding cycle after cycle. Black finish matches the aesthetic of most rifle platforms. Whether you're restoring a vintage Remington rimfire or just keeping a backup mag in your range bag, this Triple-K mag gives you a practical solution that respects the heritage of these classic .22 rifles.
