I apologize for my stupidy but something just doesn't make sense to me. I have a saiga 12s non threaded no BHO lock. According to what i have read on this forum i should have 13 parts. If i get a new american made magazine with 3 working parts im ok to convert it with a pistol grip which is what i really want to do. But what im trying to understand is that if the mag is not attached to the gun and i have it converted with a pistol grip, is it now illegal? This might be a simple question for some but i am just not understanding it. Any help will be greatly appreciated. Thank you.
