About

What it is, and why it matters

Copy a link to this section

The Caesar Guerini Invictus I Sporting is a 12-gauge over-under break-action shotgun built for sporting clays and other clay-target disciplines. It is the entry grade of the Invictus Sporting line, introduced in 2014, and is defined by the proprietary Invictus locking system, whose replaceable hardened locking cams let the gun be rebuilt to factory tolerances after very high round counts. It pairs a nickel receiver with an Invisalloy protective finish, deep-blued barrels, a tapered 10-to-8mm ventilated top rib with ventilated center rib, a DPS ultra-crisp adjustable single selective trigger, six MAXIS competition chokes, a white Bradley-style front sight, and a Turkish Circassian walnut stock with a hand-rubbed oil finish.

The Invictus name (Latin for 'unconquered') advertises Caesar Guerini's durability claim: the barrel-to-action lock uses replaceable cams engineered to endure well over a million rounds, so a worn action can be brought back to original tolerances rather than retired.

Offered with 30-inch (762mm) or 32-inch (813mm) barrels and a 2 3/4-inch chamber. Cataloged weights are about 8 lb 1 oz (30") and 8 lb 3 oz (32"), varying with wood density. Optional left-hand stock and adjustable comb are available at extra cost.

Trajectory

What the round does downrange
