Cimarron 1866 Yellowboy | .38 Special | 20-inch Octagon

The Cimarron 1866 Yellowboy is a faithful reproduction of the classic cowboy-era lever-action rifle chambered in .38 Special. It pairs period-correct aesthetics — a brass receiver, blued metal, and walnut stock — with a 20-inch octagon barrel for a traditional feel. This configuration lends itself to cowboy action competition and historical shooting events. A compact, low‑power optic such as the Vortex Crossfire II 2-7×32 will pair well with this rifle for accurate target work while staying well under a $1,000 budget.
