When I autotrigger real fast, my range decreases drasticly. A small tank that screws into the back bottle adapter and hooks up to the bottom line hose should give the liquid a place to expand and also provide a buffer of gas ready for the valve system. My gun is too loud when firing and has 'I'm over hear ready to be shot' written all over it's report. Changes the tension on the striker spring by way of a long Allen wrench stuck down the barrel. A might expensive but great for fast tune ups.
Helps keep constant velocity.
The ones for Semis are probably big time over kill but the right idea. A hose is then connected to the valve recepticle and the bottom grip recepticle to supply the gas. The hose acts as an anti-liquid system providing volume for the liquid to expand to gas. It also improves the sight picture and takes the stress off the valve assembly. Therefore when the ball leaves the barrel the gas pop behind it will effect the ball differently each time.
