But I prefer the 10. Unless you are fighting terrorists or want to impress someone, I think the fixed Milsurp 10 rd is No 1. I bought mine with a 30 rd detachable, but try shooting over your hood or prone with one. The SKS just simply handles better with the shorter mag, in my opinion. However.....I would never part with the 30 rnd mag. If we ever need to help with homeland security, it is a good idea to have a few of these.
I don't know who makes them. Whatever you do...stay away from the cheapo plastic 5 rnd mags.
