I have some Precision Mag Industries Ruger Mini 14 mags. These mags were made to the same specs as Ruger and work just like a ruger mag. Precision Mag Industries went out of bussiness due to their high capacity mags during the 1994 ban and was never started up again. Again, these things are flawless. They are 3-40 rounders and 2-30 rounders This is what I am after: AR Lower Parts Kit - really hurting for a couple of these Pmags with window (Black or that tan colored kind) - dont really need them but they look cooler than my current mags Keep in mind, I am not considering these mags as the whole crazy person "world is going to end" trade-in prices. I hope you consider that when considering a trade with me as well. Thank you!
