The Kingman Hammer 3, also known as Semi Automatic Hammer, was an inline blowback marker that did not remain in production for long. Today it is one of the rarest Kingman markers out there (not that there are a lot of rare Kingmans). It is an odd design featuring what looks like a cut off front-end from a Kingman pump functioning as the breech, detent, and barrel mount. It features a distinctive expansion chamber hanging off the right side, which is not listed in the manual from what I have seen. The manual shows the air supply line running into the side of the marker much like a Mokal Mirage.
