Good evening, would someone be kind enough to inform me of the length of a standard AA spring in a MK3 TX200 in .177? Mine has a V-mach kit fitted and I suspect that the V-mach spring in longer.
Many thanks
Simon

Don't worry about the length put it over a chrono and check the power .

How will that tell me how long the spring is?

i would suspect the vmac spec will have a longer spring. i am under the impression that the piston weight is not used with vmac, the spring would need to take up the distance the P/Weight would have taken.

My thoughts exactly. I have been thinking about a TBT short stroking kit but I don't think it will work with the V-mach spring because it is longer.
