Overview
The Winchester Model 320 is an American bolt-action .22 rimfire sporting rifle produced in the early 1970s. Chambered for .22 Long Rifle and fed from a flush-fitting five-round detachable box magazine, it featured a walnut stock with pressed checkering, a grooved receiver for scope mounts, and open sights. Its actions were manufactured in Australia, and it was made in relatively small numbers during a short production run.
