Legalize the Constitution
I found a source online for used Hk USP Expert mags, so I order a bunch of them. All of the mags are in good working order but they are filthier than a Wall Street banker. I've tried soaking them in soapy water and scrubbing the insides with a tooth brush but the grime is really putting up a fight. I'm reluctant to use Break Free or Powder Blaster on the plastic. Suggestions?
