    For Consideration when tuning power:
    It is the owner's responsibility to ensure 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 will all HW trigger arrangements 

    NOTE for legal limit: Vortek’s VacSEAL30 piston seal is not required for air rifle to work with PG4 installed. However, for the HO output force of PG4 and best fitting bore shooting power requires the Vortek VacSEAL30.
