Unless a mount is a universal type mount you are going to see pretty much Remington and Mossberg sling plates and mounts. This is because these are the most common Defense shotguns out there. As the store grows I will make every attempt to mounts for other models to the store.
I am a Stocking Dealer for some of these products and I can not sell them less then the Manufacturers Approved Price (MAP). If a Dealer is found to be selling below MAP he can loose his dealer status. Yes, other Dealers will turn you in because the competition is so brutal out there. However, that is not the reason I follow the Manufacturers rules. See, I have a sales agreement with them and that is as good as a promise or a hand shake and I will not violate my agreement.
