About

What it is, and why it matters

Copy a link to this section

The Howa M1100 is a Japanese bolt-action rimfire rifle introduced around 2020 by Howa Machinery and imported to North America by Legacy Sports International. Chambered in .22 Long Rifle, it pairs a 457 mm (18 in) varmint-contour barrel cut with HK-style polygonal rifling and a 1/2x28 threaded muzzle to a detachable ten-round steel magazine and an oversized tactical bolt handle. Marketed for plinking, small-game hunting, varmint control, and target shooting, it is also offered in .22 WMR and .17 HMR chamberings and in synthetic, OD-green, and walnut stock options.

Howa Machinery of Aichi, Japan, is best known for military rifles such as the Type 64 and Type 89 and for its centerfire Model 1500 bolt actions; the M1100 brought that bolt-action reputation to an affordable rimfire platform.

Sold in North America under the Howa-Legacy banner via Legacy Sports International. The M1100 action is also offered as a barreled action and in .22 WMR and .17 HMR chamberings.

Not a list the maker typed out: the answer comes from the mounts this firearm exposes and the interface each part needs, so it stays right when either one changes.

  • Interface standards, platforms and fit overrides
  • The same answers through the API and the MCP server

Requires a signed-in GunSpec account on the Studio plan. The answer is computed per part, so it is not part of the public record.
