-How long it took you to get it installed
I would say around 20-30 mins. but I was taking it slow making sure I had everything setup properly with the right fit.
-What your configuration was to get it working properly
At first I used a 2.5 spacer, 2 shims, and the middle spring. After firing it for a little bit the o-ring broke in and I developed a slight leak down the barrel. (this is normal and you need to move the next smallest spacer) I then went to a 2.0 spacer, 2 shims, and the middle spring and this setup has worked fine firing over 1000 paintballs.
-The type of gun you're using it on
My gun is listed in my sig.
I can't really answer this since I have a 88 CI nitrogen tank and can easily go 3+ games without needing a refill but I would assume the efficiency is lower since you need to increase the pressure. This is the case because of the stronger spring and more force that is required to move the bolt forward.
-Number of breaks/chops and type of paint used
I tested the level 10 first in my backyard with the worst paint I had. I had some old paint from summer that I got at a field and never used all of it...this stuff was in a zip lock bag for close to 6 or more months and to top it off I think it was brass eagle. I loaded around 100 balls in my hopper and fanned the trigger. I short stroked at least 3-5 times distinctly hearing the bolt stop on the balls. I only had 1 ball that broke down the barrel and wasn't from the bolt.
When I went to a field I shot over 1000 Diablo brand paint and only had 1 break down the barrel and that wasn't from chopping the ball. I assume it was because that particular ball either was cracked, had a defect, or expanded more than the others for a tighter fit down the barrel.
-Any problems you encountered
No problems so far and I have gone to the field 2 separate times. I shot at 258, 266, and 271 at the chrono with the setup the first time I went to the field. I had only 100 balls thru it and another 100 dry fires. I latter chronoed with a ref and got within 2-3 fps consistency after the setup had around 500 more balls thru it.
-Other general comments
The lvl 10 kit almost turns your gun into another. It makes chopping balls extremely hard and increases your performance because you can shoot faster without having to worry. I recommend getting this kit for anyone that has a mag. Before I had this kit I was consistently breaking a few balls if I needed to do a fast string of shots. You can almost leave your battle swap and jerk squeegee back with your tool kit.
