I have one in .22 and one in .25. The barrels in .177 and .22 are made in china, the .25 barrels are made by green mountain. Right out of the box the .25's are tack drivers. The .177's are not too bad and the .22's can be a can of worms. There are a multitude of shops doing all kinds of mods for all kinds of prices. I guess it just depends on what you are trying to achieve.
