Ive seen the replacement bolt handles for Model 10s and such but nothing for the rimfires. I have the FV with the tiny little ball forged as one piece. Is there a bolt handle out tthere for sale for the MkIIs? Or am I looking at having it turned and threaded? Had thought about buying the Bolt Lift kit from KRG and just filing down the ball to make it fit. Thanks in advance for any input.
