About

What it is, and why it matters

Copy a link to this section

The BSA Monarch is a bolt-action sporting rifle produced by the Birmingham Small Arms Company from the mid-1960s. A redesign of the earlier BSA Majestic, it used a controlled-round-feed Mauser-pattern action made in two lengths and chambered in five calibres, including the long-action .270 Winchester and .30-06 Springfield. It paired a 22-inch barrel and a fully adjustable trigger with a sporter walnut stock, and was marketed both under BSA's own name and through the American mail-order house Herter's.

BSA built the Monarch and its Majestic predecessor for the American mail-order retailer Herter's, which sold the rifles under its own Monarch branding alongside BSA-marked guns.

Built in two action lengths: the long action covered .270 Winchester and .30-06 Springfield, while the medium action covered .243 Winchester, .308 Winchester and .222 Remington. Fitted with a spring-loaded internal magazine and hinged floorplate.

Every part that mounts on this, resolved

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.

  • Every part that mounts on any firearm in the catalogue
  • 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.
