What caliber do you have? May make a difference, not sure. I recently inquired about getting one for my 338 Lapua. Most places I talked to or researched said that I would need to go to an internal box max or pay extra for a different bottom metal because the way the stock is done on the big calibers. I don't know if that was true, but I know that even a Stockade gun stock would need a different box mag that Kevin sells. All I know is nothing seemed cheap, so I ended up modifying the stock on my own to make it feel better, and then repainted to my liking.
