Scorpion has a 0.20 freeze compared to the M4's 0.17 and the Sten's 0.18. It's still a very, very nice gun - not just for the price, either. I would be satisfied for buying it at 80,000. If I would have bought this before I bought the Sten, M4, and Shipka, I could have saved myself (literally) $95. The Scorpion is my favorite gun out of the ones listed.
