Magpul recently announced that they had started shipping the Gen M3 40 Round PMAGs to their distributors. I think they are going to be a huge hit, especially with the 3 Gun crowd.
The new PMAG Gen M3 40 round mag will retail for just $19.95. Visit Magpul.com for more information. Keep an eye out at your favorite retailers for availability very soon.
The next-generation PMAG 40 GEN M3 is a 40-round 5.56×45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. Along with expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.
