i posted about a BSA Mercury challanger. i picked up last week and it is very twangy!!! so i tore it down to just the tube and trigger block. i have been trying to get the trigger block started turning and can not get it started? the maxi grip rail is butted up to the block is there some thing more i need to do to get it started turning? i have put a rubber covered rod though the hole and smacked it with a rubber mallet. with no luck. i am thinking i need to put it in a vice and get a longer rod. any tips on breaking it loose??? thanks in advance!!!
