Ruger 90683 Precision Magazine 5rd 338 Lapua Mag Black Metal

The Ruger 90683 Precision Magazine delivers reliable feeding for demanding long-range applications where precision matters most. This single-stack design ensures consistent cartridge presentation while maintaining the compact profile essential for prone shooting positions.

What Makes This Different

Unlike generic aftermarket magazines, this factory Ruger magazine incorporates the exact tolerances and materials specified for the Precision rifle platform. The single-stack configuration eliminates the feeding inconsistencies common with double-stack designs in magnum cartridges. Factory testing validates reliable function across temperature extremes from -40°F to 140°F.

Key Features

• Factory-spec single-stack design for consistent cartridge alignment
• 5-round capacity optimized for 338 Lapua Magnum dimensions
• Black oxide finish on steel construction resists corrosion
• Drop-free release mechanism prevents feeding delays
• Polymer follower reduces cartridge damage during cycling
• Heat-treated spring maintains tension through 10,000+ cycles
• Compatible exclusively with Ruger Precision Rifle chassis

Field performance demonstrates the importance of proper magazine geometry with magnum cartridges. The 338 Lapua's 3.681-inch overall length requires precise feed angle control to prevent nose diving or rim catching. Competition shooters report consistent bolt closure across various bullet profiles, from 250-grain match kings to 300-grain hunting bullets. The steel construction withstands the extraction forces generated by hot loads without deformation.
