The Invictus III Sporting features coin-­finished frame with full coverage engraving by the Cesare Giovanelli studio. It is adorned with fine engraving of Dragons and Gargoyles accented by gold. These particular units are configured in Caesar Guerini’s M-SPEC Specialist configuration with lightweight 34-inch, fixed choke barrels.

The Invictus M-SPEC Specialist is a designed for the competitive sporting shooter. Based off of world class shooter Richard Fauld’s input, the M-SPEC is designed to tackle the most demanding sporting clays targets. The barrels are fixed constrictions, Modified (.20) and Improved Modified (.25) standard with more open chokes available by special order. The top rib of the 34-inch M-SPEC incorporates a radical taper of 10mm to 6mm to be more precise on far targets.

The design of the fixed choke barrels reduces weight at the muzzle end, resulting in enhanced handling characteristics. What makes these barrels exceptional are their lightweight nature, average in at 1.2-1.4 kg, far lighter than any other 34 inch barrel on the market. The 34 inch barrels on the M-SPEC are actually lighter in weight than Caesar Guerini’s standard 32 inch mukti-choke barrels.

The Invictus M-SPEC Specialist is available exclusively at Michigan Shooting Centers in the Invictus III engraving pattern shown here.

INVICTUS: Latin, meaning: unconquerable, undefeated.

A number of years ago, Caesar Guerini engaged in a study to determine if there was a technical solution for significantly increasing the long term durability of an over-and-under action; more specifically, the problem of an “off face” condition which is created by the barrel and action wearing to the point that there is an unsafe gap between the two.

Generally speaking, locking elements in a hinge or pivot-barrel shotgun will shown signs of use due to wear of the locking bolt, forend iron and play between the receiver and barrels in the hinge pin areas. Caesar Guerini developed the Invictus system to combat the regular wear and tear you’d expect on an over/under.

Caesar Guerini’s Invictus action is the first double gun to ever overcome this issue. They accomplished this by:

1. Enlarging the size of the receiver to provide more strength and added mass, which helps to absorb recoil. The frame is about 1.7 inches wide. This extra size gives more bearing surface between the frame front and the forend iron and provides room for an extra-­wide bolt, which engages a Browning-­style bite at the bottom of the monobloc. You might expect the larger frame to look heavy, but careful shaping at the top of the standing breech maintains a light, attractive appearance.
2. Enlarging the locking bolt contact dimensions, to reduce wear.
3. Incorporating a revolutionary CAM system, which eliminates conventional hinge pins and trunnions.
4. Placing an interchangeable block in the receiver, to increase the bearing surface of the gun. This block straddles the central cocking rod about a half-­inch forward of the locking bolt. Its function is to locate the barrels against the standing breech, both vertically and laterally. The block is held by a pair of Torx screws in its recess located in the bottom of the frame. It can be removed and replaced should the Invictus start to ever shoot loose.

The result is a gun that is more durable from the start but also one that can be rebuilt and made like new at any points in its life. Caesar Guerini has effectively increased the life span of their Invictus gun by 200- 300% more than the typical double gun. We feel this is a quantum leap forward in the evolution of over-and-under shotguns.
