Seriously such an incredible upgrade for the G4.. If you don't have it yet then your G4 is not what is could and should be.. Nobody makes a better upgrades for DP guns then these guys.. The sound signiture is almost non-existant - seriously I didn't think that it would be this quiet, its so much more consistant then it was stock, the operating pressure is able to be dropped because it raises the fps, I've been able to lower my dwell, no kick what so ever and my favorite part the threading to install a guage in the end of the back cap.. So everything they say it will do it in fact does.. If you want your G4 to keep up with higher end guns then this is your first stop.. Thanks TechT for another amazing product..

This it a great product for you Dangerous Power G4. Its similar to the G3 engine. Its a simple installation. After the instalI I took the marker out for a test shoot. Immediately I noticed a change in the sound signature, and kick. I was able to lower the dwell to 8 "safe to say this is personal setting I could go lower" . And the gas effiency improved I am getting more shots per fill. The kick compaired to the stock bolt is no more. This L7 engine will remove the kick that the stock bolt has. Its a great upgrade its quality made, made in the USA. I am happy with it and I'm sure you will be too. Pick one up your G4 you wont regret it.
