Legacy Sports International .338/7Mm 5 Rd La Floor Plate & Magazine Kit

The Legacy Sports International .338/7mm 5-round long-action floor plate and magazine kit transforms your Howa 1500 into a modern, fast-reload hunting and range rifle. If you're running a Howa 1500 or one of its OEM variants—Interarms, Mossberg, Smith & Wesson, or Weatherby Vanguard—this drop-in conversion kit replaces your factory hinged floorplate with a detachable box magazine system, eliminating the need for a new rifle just to gain magazine versatility and capacity.

Installation is straightforward: remove the factory floorplate assembly and drop in the Legacy bottom metal, which includes the magazine itself and a new triggerguard housing. The polymer construction keeps weight minimal and cost reasonable, while the durable, injection-molded design handles field use without complaint. Once installed, you keep your original parts in case you ever want to restore the rifle to factory spec—a smart option if you're renting or reselling down the road.

The 5-round capacity in long-action gives you the reload speed of a detachable magazine without jumping to higher capacity. This makes the kit especially useful for hunters who want faster magazine changes in the field or shooters working with cartridges like .338 Winchester Magnum or 7mm magnums, where long-action receiver length is the standard. Additional magazines are sold separately if you want spares at the range or in your pack.

Note: this kit does not fit the Howa 1500 Superlite. Installation torque for screws is 30–35 inch-pounds.
