Ok, so....Im confused. I live in NJ. yes, I know laws are harsh here. However, Im looking to buy A new surefire Mag so is it ok to buy 15 round mags or only the ten round for my saiga rifle? I need the USA mag to get my 3 points for the 922r compliance on my conversion... Its seems as long as i dont go over 15 rounds im good? and that I can buy either and be in compliance? One more thing: I have a collapseable butt stock waiting to get pinned so it cannot move and be FIXED, but....The pistol grip Is or is not ok to add as long as I do not have more than 10 foreign parts. as I understand it
