I haven't spent much time with the mws but have owned two and shot three others. Not being a fan of large frame gassers I never gave them an honest shake or stretched them out. That being said, I have a good bit of time with their small frame guns, two of which are precision setups. One a valkyrie and one a 556. The valkyrie came from redneckbmxr and he didn't really want to come off it. He kept it over a craddock and ran it to 12 or 1300 with great results. My personal 556 precision setup is actually a stainless barrel that also came from him. It shoots as well as the 3 custom bolt gun 223s I've had. That thing is what made me actually appreciate a precision gas gun and believe there is such a thing.
