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. .029 = 29fps approx.
Joules= .7475=ft/lb.
Easy, do-it-yourself with virtually no-pre-load force on assembly. 

OPTIONAL:
NOTE for legal limit: Vortek’s ProSEAL25 piston seal is not required for air rifle to work with PG4 installed. However, it may perform higher velocities with more performance in noise damping.
