The PMAG 300 AAC Blackout/300 BLK GEN M3, . The PMAG 30 GEN M3 (NON WINDOW) is a polymer magazine for 300 AAC Blackout compatible firearms with an expanded feature set and compatibility compared to our earlier PMAGs. Advances in material technology and manufacturing processes help to make this the most reliable and durable PMAG to date. Polymer technology is constantly advancing, and MAGPUL is continually pushing the boundaries of what is possible with new materials, manufacturing methods, and quality control. What MAGPUL arrived at with the GEN M3 is a magazine that is significantly stronger in all areas. Performance in feed lip impact, spine strength, side impact, cold and hot weather impacts, and crush testing have all improved significantly over previous generations—to the point that we think you’ll find the results impressive, to say the least. Made in the USA.
