About

What it is, and why it matters

Copy a link to this section

The Caesar Guerini Maxum Impact is an Italian over-and-under break-action competition shotgun built in Brescia for sporting clays. Chambered primarily in 12 gauge (with a 20 gauge offered by special order) and fitted with 30- or 32-inch barrels, it carries a tall 17mm tapered high rib for an upright shooting stance and enhanced target visibility. It features a coin-finished steel boxlock receiver protected by an Invisalloy coating, a fully adjustable DTS trigger system, automatic ejectors, MAXIS competition choke tubes, and a fully adjustable point of impact, weight, and stock fit.

The Maxum Impact grew out of Caesar Guerini's flagship Maxum line, adapting the engraved sidelock-style boxlock action into a high-rib clays gun aimed at competitive sporting shooters who wanted an adjustable, upright shooting platform.

The 17mm high rib and adjustable comb let the shooter keep the head more upright, reducing neck and shoulder strain over long clay-target sessions. Weight can be tuned with the optional DTS Kinetic Balancer.

Trajectory

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.
