The second generation of CF 20 Magazines, the CF 20 Pro, continues to push magazine design and technology even further with its supremely reliable loading mechanism, tough material composition and curved construction. New polished aluminium inserts help reduce friction from the fins of shaped projectiles as they transverse the sharp curve in the bottom of the magazine. And ball bearings in the winder mechanism help reduce snagging and friction as the winder pays out during use. Combined with refined internal geometry this makes the CF20 Pro magazine one of the most reliable and consistent feeding continuous feed magazines ever produced.
