New Model Single-Six revolvers are the perfect small bore single-action revolver for plinking, small game hunting, or serious competition. Chambered in either 22 LR, 22 Magnum, or 17 HMR, these great single-action revolvers come in a variety of barrel lengths, finishes, sights, and grips. Single-Ten models have a ten-round capacity and feature Williams Fiber Optic sights and Gunfighter style grips. Single-Nine models also come with Williams Fiber Optic sights and Gunfighter style grips but are chambered in 22 Magnum and have a nine-round capacity. Convertible models come with two cylinders (one in 22 LR and one in 22 Magnum) for increased versatility. Hunter models are equipped with an integral barrel rib for rigid mounting of Ruger scope rings (supplied at no extra charge).
