Ruger 77/17 Magazine 6-Round Rotary 17 WSM Black Polymer

The Ruger 90521 magazine transforms the 77/17 bolt-action rifle into a reliable multi-shot platform for 17 Winchester Super Magnum cartridges. This factory-original rotary magazine eliminates single-shot limitations while maintaining the precision accuracy that defines the 77/17 series.

What Makes This Different

Ruger's rotary magazine design sets this apart from traditional box magazines through its flush-fitting profile and smooth feeding mechanism. The rotary action reduces cartridge nose damage during cycling, particularly important with the pointed bullets common in 17 WSM loads. This magazine integrates seamlessly with the rifle's action, maintaining the clean lines and balance of the original design while adding rapid follow-up shot capability.

Key Features

• 6-round capacity for 17 Winchester Super Magnum cartridges
• Rotary feeding mechanism prevents bullet deformation
• Black polymer construction resists weather and impact damage
• Flush-fitting design maintains rifle balance and handling
• Factory specification ensures perfect compatibility with Ruger 77/17 rifles
• Tool-free installation and removal for field maintenance
• Positive lock engagement prevents accidental release

Field performance centers on the magazine's ability to maintain consistent cartridge presentation to the chamber. The rotary mechanism handles the tapered 17 WSM case geometry without binding, even when loaded with different bullet weights from 20 to 25 grains. Hunters appreciate the quick follow-up shots on varmint species, while target shooters benefit from reduced handling between shots during precision work.
