Iâ??m no gunsmith.. but I will do my best to explain my little problem
On a artillery shooter Iâ??m putting together, it seems to be a conflict between some parts. The sear bar does not go enough in at the rear when the sideplate is on.
So the fireing pin does not lock up with the toggle.. Is it the sideplate that is not right, the trigger lever or the receiver? ..perhaps me?
