Review:
I decided on buying the L7 because I had read plenty of reviews and since I'm an accuracy freak, I know that the less kick a gun has, the higher chance you have of landing your target. While I tested it so far dry, I also tested it out with balls. My gun is set at 22 bps and 160 psi with a dwell of 12. It shot ropes without even the slight appearance or feel of kick. The gun was nice and steady the whole time. I had been used to shooting my friends Spyder Pilot ACS and my brothers Spyder. My ION is literally kick-less with the new bolt. I had only one ball break, and it broke all the way at the end of my 16" barrel. I had my gun set to 22bps and on psp mode so I managed to shoot ropes after the third semi auto shot. Straight shots. Also, since the dwell is low and the bolt requires less air to operate, the gun was considerably more quiet than before and also a lot quieter than my friends Spyder.
Conclusion:
So far, the tech L7 seems to be the lightest bolt on the market. It eliminates kick and increases efficiency. This is the ultimate bolt!
