||I installed this kid into a few rifles and would have to say, works great!
With proper tuning i was shooting 400fps with .43gs and hitting targets at 280 feet
What most don't realize is with a few DIY mods, and a kit such as this
Much can be achieved
280 feet was achieved accurately, 300ft was max range
A metal trigger box will still be needed to install a spring larger than a 170 safely
