Tune with
one refillable Air Source tank.
This enables you to keep the clean look of the 850 Because
these fit right under the fore stock just like the standard AirSource tanks do.
Note: These are for
CO2 Only
and cannot be used for High Pressure Air.
Doing so is not safe and will lead to serious injury.
Average .177 Muzzle Velocity
at 85°F on CO2:
(.22 is
approximately 100fps slower)
Before: 750fps
After: 790fps
Same shot count as with standard
Air Source tanks, around 170 per fill (at full power)
NOTE: You will
need an
to refill the AirSource tank with.
look at my Fill Adapter section under "Kits and
Accessories"
