Hello guys, I have purchased an Arsenal SLR107-21 and should be picking it up within 4 to 5 business days. It comes with a 5 round magazine and I would like to add about 10 thirty-rounders. I have unsuccessfully searched google and this forum for my answer, so here goes. Who has the best value on mags going right now? I honestly don't care what material they are made out of, as long as they work. I need to keep it around $150 total so looking for best mags at best value. In the AR world it's easy, just buy p-mags and be done with it. Here it seems more difficult to figure out what's good and what is junk. Thanks for your help guys.
