Cimarron 1866 Yellowboy Rifle, .45 Colt, Lever-Action, 18.5 Octagonal Blued Barrel, Brass Receiver, 10+1
This Cimarron 1866 Yellowboy is an Uberti-made reproduction of the classic brass-framed lever-action, chambered in .45 Colt. It features the open-top bolt raceway and toggle-link mechanism of the 1866 pattern with a side loading gate, paired to an 18.5 octagonal blued barrel and a full-length tubular magazine. Walnut furniture, a brass crescent buttplate and forend cap, and case-colored lever and hammer complete the period-correct configuration. Manufactured in Italy and imported by Cimarron, the barrel is roll-marked "45 COLT."

The brass (yellow-metal) receiver follows the classic 1866 architecture with an open-top bolt raceway, a toggle-link action, and a side loading gate. The lever and hammer show case coloring, and the rifle uses a straight-grip walnut stock and matching walnut forend.
The 18.5 octagonal blued barrel feeds from a full-length tubular magazine for a 10+1 capacity. The barrel is roll-marked "45 COLT," reflecting the chambering.
Sighting is traditional with a dovetailed blade front and a semi-buckhorn rear sight featuring a sliding elevator. The length of pull measures 12.9, offering a classic lever-gun fit.
Trim and furniture details include a brass forend cap and a brass crescent buttplate, pairing with the blued barrel for a timeless two-tone look. Italian Uberti manufacture imported by Cimarron ensures a faithful 1866-style configuration.
