The 1866 Yellowboy from Cimarron draws buyers who want a period-accurate lever-action reproduction. The brass receiver is the visual centerpiece, and owners consistently note Cimarron's fit and finish is solid at the price. The .32-20 Winchester chambering appeals to cowboy action shooters and small-game hunters who prefer light recoil.

Functionality is generally smooth after a break-in period. Some owners report the action needs a few hundred rounds to fully smooth out, which is typical for this style of reproduction rifle. The walnut stock quality draws positive remarks, with wood-to-metal fit described as tight on most examples.

Opinion divides mostly on the .32-20 Winchester chambering. Cowboy action competitors who already reload for the caliber find it economical and accurate. Those outside that community sometimes wish this model were offered in a more common caliber, making ammunition sourcing simpler.
