Unimag Multiple Caliber Magazine 30rd

Ross & Zheng Engineering is pleased to announce the second generation of the UNIMAG multi-caliber magazine. Over most of last year, the Ross & Zheng Engineering directed research towards a fitting issue that was observed in most of the first production run, and carefully integrated the solution into the mass-production. By selecting a more optimal welding dimension and fine tuning the "coating" process, you can rest assure that your magazine is easy to load and now drops free at the push of a button.
Capacities with various calibers listed below

• .223 Rem / 5.56 NATO / .300 BLK / .204 Ruger / (All .223 Parent Case) - 30 Rounds
• 5.45x39 - 29 Rounds
• 6.8 SPC - 26 Rounds
• 7.62x39 - 25 Rounds
• 6.5 Grendel - 24 Rounds
• .458 SOCOM - 12 Rounds

In development for over two years, this magazine has been extensively live fire tested on both full and semi-auto rifles. A stunning variety of rifle brands, and every type of rifle that accepts a STANAG type magazine, were tested with more than 30,000 rounds of 5.56, 7.62x39, 6.5 Grendel, 6.8 SPC, and more. From new bullpups like the IMI Tavor and Kel-Tec RDB, to home-built, budget parts kit 7.62x39 AR-15s, no stone was left unturned. Unimag even feeds 12 rounds of the mighty .458 SOCOM! When the design was perfected and the magazine deemed ready for production, RZE refused to cut corners. The patented stainless steel body has been finished with salt bath nitride, just like a match grade rifle barrel. The stainless steel spring pushes a patented articulated anti-tilt follower that is one of a kind. The magazine is capable of accepting and feeding rounds with an overall length all the way up to 2.31"!

This magazine is perfect for machine gun rental ranges, hunters who bring multiple AR uppers with them in different calibers, and preppers who want to simplify their supply chain and maximize flexibility. If you like the advantages of unusual calibers like 6.8 SPC and 6.5 Grendel but hate the additional cost of outfitting your rifles, buy this one magazine and leave the world of finicky, proprietary mags behind forever! To prove their worth, if you aren’t satisfied with the performance of your Unimag, RZE offers a 30-day money-back guarantee!
