Im looking for some good 5 round magazine for my 7.62x39 AR. What are some good brands that wont jam my gun? I got some C-product 5 round off ebay last year, but they still have feeding issues and jam my gun with every shot. The springs on them are still pretty stiff. I got some 30 round magazine that works perfectly, but I dont know what brand they are since there isnt any markings on them. Would a 10 round magazine work better than a 5?
