Just got a new TM MP7A1 and on Green gas its shooting around 348fps on 0.2g at 11 degrees. I haven't seen any reviews where its been shooting this hot.
I've since replaced the nozzle with an enhanced guarder one and started using white/blue gas, and cranked the hop a bit which gets me safely under the limit for my field (350fps on 0.2g or 1.14J). I don't have anywhere to set the hop until gameday so I just had to guess.
Could it be that I am overfilling my mags which is causing this? If so how long do other people fill them for? (I've never used 2 stage valves before).
Any other tips for lowering the FPS or filling mags?
