What would be a good selling price for a Mossberg 500 with wood stock, adjustable cheek riser and cantilever slug barrel if I was to sell to a LGS or through my gun club? I am debating on buying a Beretta A300 in camo with the green receiver for $650 and would like to let the Mossberg go to do so. I have never sold one of my guns so looking for some insight. Another part of me says keep the Mossberg and slug barrel as a backup deer combo but I already have 2 deer rifles. I have also thought about giving the slug barrel to a buddy who has nothing to deer hunt with.
