I'm still waiting for them to ship my ERB. It has been almost a week.... The wife is going to let me buy 10 on the 14th...so I'm pretty excited! I have 21 regular metal ones...more than half of which came from my buddy when we were out a Ft.Leonard Wood. He had some left over from one of his deployments to Iraq...I like that my mags have stories behind them lol I guess you can never have too many mags though!
