THIS IS AN AIRGUN ONLY PART

Remember it is recommended that you order your suppressor one size larger for shrouded barrel PCP’s.
If you have a .22 caliber shrouded barrel PCP, you’ll want to order a .25 caliber suppressor.
The .177/.22 is for shrouded barrel .177 or direct barrel threaded PCP’s in .22.
The .22/.25 is for shrouded barrel .22 or direct barrel threaded PCP’s in .25.
The .25/.30 is for shrouded barrel .25 or direct barrel threaded PCP’s in .30. The exception to this rule is the Gauntlet .30 which is shrouded but because of the unique end cap, marries the barrel and shroud at the end.
Gauntlet STK
THIS ITEM IS NOT DESIGNED FOR THE GAUNTLET 30
IT HAS ITS OWN HAMMER PRELOAD ADJUSTER STOCK
Kits available to fit Gauntlet 1, Gauntlet 2, Gauntlet 2 SL, or Gauntlet 2 Limited 22/25, variants.
The single largest performance increase modification item for the Gauntlet. The Super Tune Kit allows complete power adjustment, opening the possibility of higher or lower foot-pounds (FPE) for whatever the user desires. Do you need only 5FPE? No problem back off the adjustment using a 5/64″ allen wrench and you are only delivering 5FPE and will realize over 200 shots on a stock bottle fill of 3000PSI!
Want 27-30FPE for dropping that 20lb trash bandit, no problem, crank up the adjuster using a 5/64″ allen wrench and you instantly have the power necessary for either long range or high energy delivery on target. The use of a chronograph is required to know the rate of travel of the projectile. (Power examples given are the .22 caliber version Gauntlet 1)
For the Gauntlet 1 and Gauntlet 2. Be sure to select the proper generation, as there is a difference, and improperly selected kits are not returnable.
BE SURE TO SELECT THE CORRECT GENERATION GAUNTLET
