A bit of an upgrade in modelling and downgrade in complication this is a simple model of a self contained steam powered rifle. It's missing a couple of bits, such as the strap that holds the replaceable tank in place and the duel lenses for the sniper model, but this is basicly it. Also, once again, no tubing as it's more complicated than I can make it right now. Though I'm proud of how the stock came out. Operating Instructions: 1: Push cover lever up and forward to locking position. 2: Insert single (1) ball round. 3: Return cover lever to rear locking position. 4: Rotate primer handle a full 180 degrees from close position. (Warning: This places weapon into full firing mode. Caution is advised.) 5: Depress secondary primer button by applying pressure to handle. This is done by holding the rifle in a standard firing position. The weapon is now fully primed and ready to fire. 6: Take aim. 7: Depress trigger. Upon trigger depression the primer lever will swing back into pre-primed position and the rifle will fire a single round. 8: Repeat steps 1-7 as required.
