Winchester USA 5.56x45mm ammunition (brand part no. WM855500) loads the well-known 62-grain Green Tip bullet for shooters who feed AR-platform rifles by the case rather than the box. Winchester builds this load around a full metal jacket bullet with a steel penetrator core beneath its green-tipped jacket, the same profile that made the Green Tip designation a household name among AR shooters. The chambering runs in both 5.56 NATO and .223 Remington rifles, and the brass cases are reloadable for handloaders who want to recover their brass. Packaged in a 1,000-round case, it is built for range days and training cycles that go through ammunition fast. In rifle ammunition bought by the case, this is a standard choice for AR owners.
