Armalite AR10 20rd Gen II Magazine 10607002

This is the perfect large-frame AR magazine; even with standardization moving towards the inferior DPMS/PMag, there is not one single magazine out there that can compare in durability and reliability - not to mention allowing long cartridge overall length - to the B-pattern ArmaLite standard. I am so happy that ArmaLite continues to strongly support this platform, and will continue to do so! I have literally dozens of these and have, as of now, 39,000 rounds through my main AR-10 (quite a few through my other AR-10s) using these magazines, and even in mud, sand, blowing grit, and every other lousy condition, and with the gun filthy and hot and the ammunition caked in dust inside the magazines, I have literally never experienced one single failure ever.
