Brutuz, those are two very nice videos that you made. Thanks for linking them to this thread, very cool. The results of your rifle tune are exactly what I am looking for - a .22 with low cocking effort and mid 600 -700 fps. How was the rifle before you tuned it? Besides polishing the spring, did you do anything else to it to lower the power?
... make sure you get the second adjustment screw in the trigger. ... i hated the to5 trigger but mike sent me a metal one with the second adjustment screw ...
I usually have one or two on hand ready to drop in, would like swaps for the trigger if possible....that way I have extras on hand...
