The TorkMag-50’s dual spring, balanced torque system and self-leveling follower actively equalizes force on the nose and tail of loaded rounds, preventing the bolt-over-base and bullet nose diving malfunctions that have plagued large magazines. Because their workload is shared, both springs can be scaled down without sacrificing optimum resistance and reliability. The springs’ reduced footprint beneath the follower allows our design to be highly space efficient. Follower is also self-lubricating and self-cleaning. No-Slip Grip Bars on front and rear walls. Successfully tested without any modification: 5.56x45mm/.223 Rem, .300 Blackout, .458 SOCOM, .50 Beowulf and .450 Bushmaster. Holds 18 rounds of .458 SOCOM and .50 Beowulf. Holds 21 rounds of .450 Bushmaster.
