ProMag RUGA16 Ruger 10/22 Magazine 23rd .22 WMR Smoke Polycarbonate

The ProMag RUGA16 extends your Ruger 10/22's capacity to 23 rounds of .22 Winchester Magnum Rimfire, delivering sustained shooting capability for extended range sessions. This smoke-tinted polycarbonate magazine transforms standard rimfire performance into a high-capacity platform. Built specifically for .22 WMR chambering, it provides reliable feeding through transparent polymer construction that allows instant round count verification.

What Makes This Different

Unlike standard 10-round rotary magazines, the RUGA16 utilizes a straight-stack design that maximizes capacity while maintaining the compact profile essential for field use. The polycarbonate construction reduces weight by 40% compared to steel alternatives while providing impact resistance rated for repeated drops on concrete surfaces. Smoke tinting offers UV protection that prevents polymer degradation during extended outdoor storage.

Key Features

• 23-round capacity for .22 Winchester Magnum Rimfire cartridges
• Smoke polycarbonate body with steel internal components
• Transparent construction allows visual ammunition count
• Drop-free design with positive magazine release engagement
• Anti-tilt follower prevents feeding malfunctions
• Heat-treated steel spring rated for 5,000+ compression cycles
• Compatible with factory Ruger 10/22 magazine wells

Field testing demonstrates consistent feeding across various .22 WMR loadings, from 30-grain hollow points to 50-grain full metal jacket rounds. The magazine functions reliably in temperatures ranging from -20°F to 140°F, making it suitable for year-round varmint hunting and competition shooting. The polycarbonate body resists cracking under rapid temperature changes that can affect traditional polymer magazines.
