The shortest 40rd AR mag on the market!

TorkMag’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 15 rounds of .458 SOCOM and .50 Beowulf. 

Length: 9.0" (228.6mm)

U.S. Patent 9,062,924
Made in the USA.

    I was somewhat skeptical about the design of these magazines, whether they would be even remotely as reliable and durable as other proven mags on the market. I picked up a couple of the 40 round TORKMAGS to test out. The price was excellent, so I had nothing to lose. These mags performed flawlessly! Over the past month I have put 1000 rounds downrange between the 2 mags. M855, M193, steel case,..... It all fed perfectly, both slow fire and mag dumps. I never had a single magazine related malfunction. I tested them in several rifle makes: LMT, Larue, Daniel Defense, and a CZ Bren. These passed multiple drop tests ranging from 1/4 to full mags without issue in grass, hard packed dirt, and in gravel. I can whole heartedly recommend the TORKMAGS, at least as far as the 40 round mags are concerned. I would expect the 35 and 50 round versions to perform just as well. I plan to order both of those next to test as well. Most importantly, would I trust my life with these mags? I can confidently say that YES I would. These performed as well as or better than any of a dozen or so magazine brands I've tested in a similar fashion. So order these with confidence, you will not be disappointed.
