The Ammo Boost 10rd Detachable Magazine Conversion Kit transforms your Howa 1500 rifle into a faster, more versatile shooter by swapping out the factory floorplate for a modern detachable magazine system. If you own a Howa 1500 (or one of its clones—Interarms, Mossberg, Smith & Wesson, or Weatherby Vanguard actions)—and you're tired of reloading through the action or managing a hinged floorplate, this drop-in kit gives you genuine magazine-fed convenience without buying a new rifle. The 10-round capacity option maximizes your magazine versatility, whether you're at the range, in the field, or training.
Installation is straightforward: remove your factory triggerguard and floorplate assembly, drop in the new polymer bottom metal, and secure it with the included hardware. The entire kit is built from durable, injection-molded polymer that keeps weight low and cost reasonable while standing up to hard use. Because it's truly a drop-in design, you can save your factory parts and return the rifle to its original configuration anytime—no permanent modifications. Just apply the specified torque (30–35 inch-lbs on screws) and you're ready to go.
The Ammo Boost system is available in both 5-round and 10-round capacities to suit different use cases and local regulations. The 10-round kit works with both long-action and short-action Howa 1500 platforms. Note: this conversion kit is not compatible with the Howa 1500 Superlite variant. Additional magazines are sold separately, so once you've committed to the system, building a rotation of spares is simple.
Whether you're a dedicated long-range hunter, a tactical shooter, or someone who simply wants faster, smoother reloads than a hinged magazine allows, the Ammo Boost 10rd kit delivers the modern ergonomics and capacity your rifle has been missing—without the need to start over with a new firearm.
