Yes they're shit, buy TM, or KWA My almost stock TM 4.3 Shoots in almost any condition... from near freezing to being run hard and put away wet. They only thing that has gone on in in two years that I have had it, I bought is used, is that sliver plate that manages the hammer cocks and it was only bent. I bent it back and works like a charm.
