For Consideration when tuning power:
It is the owner's responsibility to ensure the legality of their air gun power output.
Vortek’s Location of testing is 578 Feet.Above.Sea.Level. (F.A.S.L)
For every 1000ft above or below will be approximately .029 difference in velocity, thus foot-pound (Ft/lb, Joules) of shooting energy.
1000 F.A.S.L.x .029 = 29fps approx
Joules= .7475=ft/lb

Easy, do-it-yourself with virtually no pre-load force on assembly.
Works in all Diana trigger arrangements except EMS air rifles.
