So it seems the shaft assembly is wrong with them, they are not sold anywhere in Revain to my knowledge. I picked this up on September 2nd, it's now September 21st, the gun has stopped working and I use them quite often at work, I understand that they wear out, but if the husky lasts at least 2 months before it goes bad and fails the company's main brand that makes the same product. Not good. So if you're buying a branded air hammer, I recommend looking for an "air valve assembly" and buying at least 2 or 3 of them. If your gun makes a ssssh sssssh noise in the air, the gun isn't bad, it's the part that went bad. The gun was lubricated daily, not dropped, should last at least 3 months. I don't recommend that at all
