What’s Included
- Ithaca Single Barrel Trap Knick Model Grade 4E 12 Gauge shotgun
Factory engraving highlights include scrollwork on the receiver, top lever, and trigger guard, plus a starburst motif panel on the right side. The Grade 4E treatment pairs well with the Knick single-barrel trap lineage associated with Frank Knickerbocker, offering classic American trap-gun styling and details.
The single 12-gauge barrel wears a ventilated rib with rectangular posts and a matted surface to cut glare. The barrel has been professionally shortened from 34 inches to approximately 32.14 inches, and there are no visible choke-tube threads at the muzzle. A red front bead provides a clear aiming reference, and the ejector is well timed.
The break-open, top-lever action uses a single trigger and is configured for one round. The action drops with some resistance, barrel fit is decent, and the firing pin is in solid shape, reflecting a serviceable mechanical setup suitable for continued range use.
The walnut stock set includes a pistol-grip butt with a Monte Carlo-style raised comb and fleur-de-lis checkering accents, paired with a beavertail forend featuring wrap-around checkering and an inletted metal escutcheon. The comb height has been adjusted, and an aftermarket LimbSaver recoil pad is installed, yielding a 13.75-inch length of pull. There is a slight left-hand cast to the stock.
