Who let the Bulldogs out?
I was talking to a friend of mine who recently picked up a Bulgarian SA93 and was looking to start taking it the range over the weekend. He mentioned that some of the AK mags he had for his new rifle didn’t seem to fit properly. I told him that he might want to go through his AK gun collection and match the mags that work to the guns. I went through this ordeal several years ago and sometimes people think that stockpiling a bunch of surplus AK mags means comfort, but the reality is that every magazine manufacturer and every gun manufactuer are going to have various tolerances concerning the magwell.
One way to deal with this issue is to test your mags with a particular gun, I recommend that people pick up something like the Bulldog Extreme Assault Case for every semi-auto they own. Rarely do people talk about magazine storage, but every Bulldog Gun Case that was designed for an AK or AR type of rifle can store magazines and although it may not hold more than half a dozen mags or so you’ll know the magazines that are in the bag work for the gun if you do your testing.
