Here it is in a nutshell:
An Autococker is a paintball marker Made By Worr Game Products (WGP)
It basically is exactly as it sounds. It is a pump-action marker that "Auto"matically "Cock(er)"s itself through the use of the pneumatics on the front of the gun. The first auto cockers came out in the early to mid 90's and have been widely used on the tournament scene, and has had MANY different forms. Several company's have created their own custom models built on the Cockers body, and it is without a doubt one of the most customized guns there are in the paintball markerplace today. If you wantto learn more about them there is a great forum here on the nation:
They do require some TLC in areas that some may feel is "difficult" or is perhaps troublesome, but once you learn the basics (and believe me, after the first day or two, you suddenly realize it IS basic.) it is really easy to ake care of, and extremely reliable as well.
I hope this helps...
