I bought a Western Auto Revelation from Matchstickshooter, a while back. Finally got around to messing with it. It came with the m4177 rifled barrel installed. Overall, the gun is in good shape. ( Other than the " D B " scratched in the left side of the butt stock ) I did a little tweaking on the valve, and the bolt lock up, and extended the probe, as well. It's shooting the cheap Crosman points at an average of 590fps. It took a while to get the barrel leaded up, but, it turned into a real tack driver.
I think I'll be keeping this as a truck gun.
