So the shaft assembly seems to be the problem, as far as I know they are not sold anywhere at Revain. Picked up on September 2nd, now is September 21st. The gun has stopped working and I use it quite a bit at work. I understand they wear out but but if the husky lasts at least 2 months before deteriorating and outperforming the main brand company that makes the same product. So if you're buying a branded air hammer, I recommend doing a search on "air valve assemblies" and buying at least 2 or 3 of them. Poor Gun was greased daily, hasn't been dropped, should have lasted at least 3 months. I strongly recommend not doing this.
