Description
Few lever guns turn heads at the range like a brass tacked Yellowboy. The Cimarron 1866 Pawnee Carbine is a reproduction of the Winchester 1866 spotted carbines carried by warriors of the Sioux and other Plains tribes, who decorated their prized rifles with rows of brass tacks. The most famous example belonged to Sioux Chief Pawnee Killer, whose carbine wore more than 100 tacks. Cimarron captures that look with a walnut stock and forend dressed in traditional tack patterns, set against a gleaming brass receiver and a deep blued 19 inch round barrel.
Why the 1866 Pawnee Carbine Still Matters
The 1866 was the gun that fixed the Henry rifle's biggest headache. Nelson King's loading gate on the side of the frame, paired with a proper wood forearm, turned the Improved Henry into the first true cowboy lever action. Its slab sided profile rode well in a saddle scabbard, and the carbine version far outsold the rifle back in the day. Native Americans called it the Yellow Boy for its brass frame, and Cimarron's version keeps the smooth toggle link action that made the original such a fast handling repeater.
Shooting the Cimarron Pawnee Carbine
Chambered in .45 Colt, this carbine holds 10 rounds in the tube magazine plus one in the chamber, feeding through the King's style loading gate just like the originals. The 19 inch barrel with 1:16 twist stabilizes classic bullet weights well, and at 37 inches overall and around 7.4 pounds, it swings quick and soaks up recoil nicely. It is a natural for cowboy action matches, plinking with mild loads, or working brush country where a handy carbine earns its keep.
A Cimarron Yellowboy Built by Uberti
Cimarron partners with Uberti in Italy to build these, and the fit and finish shows it. The case hardened lever, polished brass, and hand fitted walnut give it the feel of a rifle from another era. Whether it ends up over the mantle or in regular rotation at the range, this is one of the more distinctive lever actions you can put your hands on.

Frequently Asked Questions
Who makes the Cimarron 1866 Pawnee Carbine?
Cimarron partners with Uberti of Italy to produce this carbine. Uberti is widely regarded as one of the best makers of Old West reproductions, and Cimarron holds them to tight standards on fit, finish, and historical accuracy. The result is a faithful recreation of the Winchester 1866 spotted carbine.
Does the Pawnee Carbine shoot .45 ACP or .45 Colt?
This carbine is chambered in .45 Colt, also called .45 Long Colt, the classic revolver cartridge of the Old West. It is not chambered for .45 ACP, so make sure you pick up the right ammo. Pairing it with a .45 Colt single action revolver makes for a classic one-cartridge setup.
Is the Cimarron 1866 Pawnee Carbine good for cowboy action shooting?
Yes, the 1866 pattern is a favorite in cowboy action circles. The toggle link action cycles fast and smooth, the 19 inch carbine length handles quick between stages, and the 10 round tube keeps you loaded for most course requirements. The brass tack decoration also gives it plenty of character on the firing line.
What do the brass tacks on the stock represent?
Plains tribes often decorated their most prized rifles with brass tacks, and the 1866 Yellowboy was among the most sought after. Sioux Chief Pawnee Killer famously added a tack to his carbine for each Pawnee he defeated, ending up with over 100. Cimarron's tack pattern honors that tradition and gives this carbine its distinctive spotted look.
