Having more trigger time behind your gun is never a bad thing, especially when it's an easy-shooting pistol-caliber carbine like the CZ-USA Scorpion. To give shooters a chance to run their gun longer, Pro Mag developed its CZ Scorpion Polymer Drum Magazine. This Pro Mag CZ Scorpion Polymer Drum Magazine is made using a proprietary type of Zytel-based polymer originally made by DuPont. The housing is made from this material, while the upper feed tower features a carbon-steel lip reinforcement that's overmolded to aid in durability and lubricity. The drum is completed with an injection-molded magazine follower that tops a spring made from heat-treated stainless steel. The Mfg: Pro Mag
