Microtech AR-15 30rd Magazine 5.56/.223/.300 Black - XM30-E4

So here is the story - Microtech Small Arms Research (MSAR) was a subsidiary of Microtech Knives that operated on the cutting edge of the firearms industry for a number of years. During that time they produced ( in my opinion ) some of the finest firearms and accessories ever made in the U.S including one of the highest quality AR-15 30 round mags in existence. Unfortunately the owners decided to discontinue the firearms division to concentrate on their first love which was and is their very successful knife company... You can look them up... it's worth a google. Recently at a trade show I had the pleasure of meeting a retired distributor who still had a fair number of these magazines, still brand new in the factory packaging, stored away in his storage warehouse in the original master cases. The full story of why he still had them is personal in nature and not at all germane to mags themselves, but long story short we were able to agree to a deal to purchase all of them which was good for him, good for us, and ultimately good for you. If you are not familiar with these fine mags I encourage you to try them. They are very similar to Magpul in both appearance and quality. 30 Round Capacity, E4/AR-15/M16 Compatible, 5.56x45mm/.223/.300BLK Magazine

Designed for AR style firearms that use 5.56/.223 or 300BLK, these magazines are compatible with a variety of AR style host firearms and have a unique riser that allows for positive contact with the last round bolt hold open in all host firearms. Comprised of polymers that are UV, heat, chemical, and impact resistant and molded to provide for better grip, these mags are intended to withstand even the harshest conditions.  A corrosion resistant body spring and self-adjusting follower also help to increase durability and performance.
