Honestly I have owned 3 NT's and all of them shoot incredible. The biggest thing you need to remember with an NT is the reg functions with the gun like a cockers reg would. Though it does have bearing on the velocity it is mainly used to control cycling pressures of the gun. Your best bet is to buy an NT reg tester, set your reg to 110-115psi, toss the blue or green insert in if you have it (the bolt tip one, not the spacer), and run an 84 or an 80 barrel back underbored. This should put you around 290 fps. Make sure to stay on top of cleaning the marker and lube it every time you play and run fresh batteries every month or whenever it tells you that its low. You shouldn't have a problem what so ever.
