i purchased a ff2 couple yrs. ago and decided to mount it on mossberg ssi-1 with base already on barrell. my problem is it will not snuggly mount to base. i have tried squared and round side of pin with no luck as it is still wobbly on base . also have protector from gentleman on this site that is not working out either. any tips,thoughts, or solutions appreciated.
thanks,swampfox
