This is a full tune. I suggest this to most guys till you get a feel for the gun.
This is the same foundation tune used in all the subsequent conversions, so even if you choose to later go to HPA, the tune will not be needed again. So you can then deduct the price of this tune from the Conversion.

Average 177 Muzzle Velocity at 85°F on CO2: (.22 is approximately 100fps slower using 14.3gr CP)
Before: 750fps (7.9gr CPL)
After:   790fps
Shot count: 170 (at full power) per Air Source tank.
Depending on your current HPA setup, this tune could add over 100fps.

 Take down of the action and check and correct any of 
 the "common" issues that might be found.
 This will include:
 1. Shim for the barrel if  "sloppy". Most are a bit.
 2. Full breech and port mod.
 3. Check and replace o-rings (usually not needed on a new gun)
 4. Adjust / center probe on Breech
 5. de-burr and lube the action and hammer ways.
 6. Replace Hammer spring with Upgrade spring and new guide.
 7. Fit any other parts included in the tune. (discuss with me first)
 8. Foam fill stock to reduce that hollow sound.
 9. Put grub screws into empty sight screw holes if sights were
     removed..
10. Flow Mod Valve ** NEW **

Note: Any parts removed from your gun to facilitate the tune
          or Conversion will be shipped to you with the rifle.
