Muzzle Mack Air Systems presents the "new"
“Extended Bulk Fill Valve Adapter”
The new design is 1.5” longer than the Discovery and other aftermarket front valve halves commonly used in converting a 22xx series air gun to Bulk Co2 or PCP/HPA.
This places the seals before the “Safety Warning” roll stamp.
This “Roll Stamp” area is known for its catastrophic failure when converting a 22xx series Air Guns to HPA/PCP and running too much pressure in the gas tube. The Roll Stamp is much like the “pineappling” on a grenade.
Machined from solid “Free Machining Brass” bar stock.
Larger 7/16” ID is reamed to size for a smooth boar up to the spring seat for increased volume vs. the ¼” boar in a “Discovery” valve.
Double Buna90 O-rings (The best for Co2, Nitro & HPA).
With the Extended Bulk Fill Adapter you can have a safer Dual Fuel Air Gun when used with a Discovery or Aftermarket "Fill Adapter".
Other recommendations for HPA/PCP use:

Be sure to check out our 62 ci Regulated Fill Tanks... On Sale Now! $99.99... that is $50 less than the Benjamin Fill Tanks...
Note:
Trimming of the front trigger group mounting screw may be required. (on 2260 Rifle… a washer may be used if the screw bottoms out on the valve.)
Do not drill in valve tube or reduce the screw relief area. Wall thickness is critical.
O-rings come pre-treated with HPA/PCP Safe Silicone Grease
!!!Safety Warning!!!
DO NOT EXCEED 2000 psi fill pressure.
Modifying any air gun is dangerous and you do so at your own risk.
Modification and Installation should be done by an experienced Air Gun Smith.
Never work on an Air Gun that is pressurized or loaded.
All ways keep the muzzle pointed in a safe direction. |
