If you are looking to hold the most rounds you can in a magazine, then checkout the X Products Drum Magazine. This X-10 magazine is designed to fit Armalite .308 Winchester rifles. It is made out of aluminum, holds 50 rounds of ammunition, and comes in a black finish. The magazine easily loads and unloads by operating the front hand wheel. Unique to this magazine's design is a patent pending feed device that allows the magazine to run massive spring pressures without effecting the firearm's bolt operation.
