Pro Mag Industries Magazine for Ruger Mini-30 Features The ProMag Magazine for Ruger Mini-30 is built from steel giving it the durability and reliable feed lip rigidity that polymer magazines can struggle to match over years of hard use. Chambered specifically in 7.62x39mm it is sized to match the Mini-30 s action and feed geometry for dependable cycling shot after shot. The 20 round capacity doubles the ammunition on hand compared to a standard 5 or 10 round factory magazine useful for range sessions hunting or home defense scenarios where reload frequency matters. Steel construction also holds up better than polymer to the compression forces of a fully loaded magazine over long term storage. The nickel plated finish on this magazine adds a layer of corrosion resistance beyond what a bare steel magazine offers helping it resist rust from humidity or occasional exposure to the elements during hunting trips. The bright nickel finish also makes it easy to visually distinguish from other magazines in a range bag or safe. As a direct fit magazine for the Ruger Mini-30 no modification is required for proper function. For Mini-30 owners looking to add a reliable spare magazine or replace a worn or lost factory magazine the ProMag steel 20 round magazine is a straightforward durable option.
