WARNING: Recently my friend had some problems arise with his M2. He contacted Sigarms and basically got the cold shoulder, they said there was nothing they could do for him and he was on his own. He said the customer service rep talked with an air of distaste and was borderline rude. Really unprofessional. Apparently they don't support the M2 anymore, neither does Mauser. They could've just said that. I still think it's a good gun, but if you get one make sure you know where to find a gunsmith, if it should, like anything with moving parts, break down or have a malfunction.
