I forgot to say why, which is asked for in the title of the thread.Eclipse Autococker with (non electro) Blade frame.
First, shooting an Autococker is just awesome. That moving block on the back just has a certain....something to it, that you either hate or love.
Timed well, an AC has an incredible sweetspot and uses a very low pressure (I demonstrated this often by shoving my finger down the feedneck and cycling the gun. Didn't hurt...)
Also, the Autococker pixies just made the gun shoot further and more accurate. Scientific fact.
