I am restoring a Riverside Arms Co. Model 315 in 16 Gauge. I know you may be asking yourself why? The gun has no significant historical or monetary valve, but was looking for a project and found this gun for $150. The bores are like looking into a round mirror. The action locks up tight with the top snap leaver sitting at about 5 o'clock when the barrels are closed. I will need to find a new stock as the original is beyond repair, but the fore-end is in great shape and should refinish just fine.

This is the start.

The stock is shot.
One question is that when the action is closed there is a slight misalignment between the left barrel and the receiver.


Should I try to file the receiver to align with the barrel or leave this like it is?
