Here's my MP7, I've used it for a couple of games and am loving it so far. Couple of external attachments but have yet to tinker with the internals. I do worry about common issues such as nozzles and backplates cracking but have had no issue yet, so am wondering if I should get spares handy or are there worthwhile upgrades/fixes?
Anyways, I carried out a few tests on the chrono and here are my results.
I was surprised to see a gain of around 25fps when increasing the hop-up from off to fully on. I expected it to decrease due to the friction but I imagine it actually creates a better airseal therefore more FPS? I confirmed this with my MWS too.
Also to note ASG Ultrair gave around 15fps lower compared with Nuprol 2.0 so that is handy to know if you chrono above 350 on a hot day this summer.
I will be carrying out some range testing this weekend with a range of BB weights from .2g to .4g so will report back on that!
