The Legacy Sports International 300 Win Mag 5-round conversion magazine kit transforms your Howa 1500 rifle from a traditional hinged floorplate to fast, modern detachable-box-magazine operation. If you own a Howa 1500 and want quicker reloads without buying a new rifle, this drop-in kit gives your gun genuine tactical versatility while keeping cost down. The kit includes the 5-round magazine and a complete bottom metal assembly—everything needed to swap out your factory triggerguard and floorplate in one straightforward installation.

The entire system uses reinforced, injection-molded polymer that's tough enough for field use while staying light and affordable. Since it's a drop-in design, installation takes just minutes and requires no gunsmithing. Better yet, you can save your factory parts and return the rifle to its original configuration anytime. This makes it ideal for hunters who want the speed of a detachable mag for follow-up shots or quick magazine changes without permanently modifying their rifle.

The 300 Win Mag version fits standard long-action Howa 1500 rifles chambered in that cartridge. It also works with Interarms 1500, Mossberg 1500, Smith & Wesson 1500, and Weatherby Vanguard rifles—all of which share the Howa 1500 action. Note that this kit is not compatible with the Howa 1500 Superlite. Additional 5-round and 10-round magazines are available separately if you want spares.
