You might also try Cole’s fine shotguns. I think they are the largest dealer for CG in North America. They have a whole dept for fine shotgun repair and modifications. I forget the brand of replacement stock they specialize in but they are nice. Not sure how far backlogged they are tho? I want to say the mothership is in Naples Florida? I know they have 2 or 3 hubs around the Country. You won’t find any Mossberg or Remingtons at their stores tho! Hah!
