Dear C Hing,
If you could have done a so call complete modification into a AEG (eg. Marui M4 platform) spending 8K or 8K+! Then you should have known what performance is upto!
So far I don't h ...
sorry ching a fully modified aeg only cost $5500 include the gun price at 20F and could shoot a coke can at 30m and a human target at 60m. However I bet a not modified ptw could not do that unless it is modified and cost $15000 in toatal. Everything is physics no matter how "godness" is a ptw, it still is a toy and has a limit for example, can shoot a coke can at 30m, of course I am talking about power under than 2j. Assume both barrel is 300mm long.
Energy (in joules) = 1/2 mass * velovity^2
s = ut + 1/2 at^2
s = distance
u = initial velocity
v = final velocity
a = acceleration
t = time passed
