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. Recrown Barrel to improve accuracy
4. Check and replace o-rings (usually not needed on a new
gun)
5. Adjust / center probe on Breech
6. de-burr and lube the action and hammer ways.
7. Replace Hammer spring with Upgrade spring and new
guide.
8. Fit any other parts included in the tune. (discuss with
me first)
9. Foam fill stock to reduce that hollow sound.
10. Put grub screws into empty sight screw holes if sights
were
removed..
11. Flow Mod Valve
12. Trigger mod.
Note: Any parts removed from your gun to facilitate the tune
or
Conversion will be sent to you with the
rifle.
