Still the best choice - Ruger Magazine MINI-14 223 5 Round

While higher capacity magazines means more time shooting and less time reloading, the 5 round Ruger factory magazines are still my favorite. The flush fit makes the rifle easier to handle, especially firing prone or off of a bench. The magazine feeds reliably, even with long bullets, such as 77 grain BTHP, which can be problematic in the thicker-bodied plastic magazines.
