This product is a collection of precisely manufactured components designed to modify the stock dimensions of a shotgun. These kits typically consist of polymer or metallic shims that, when installed between the receiver and the stock, alter the gun’s drop and cast. For example, inserting a thicker shim at the top of the stock attachment point will increase the drop, effectively lowering the point of impact for the shooter.
Altering a shotgun’s stock dimensions is crucial for achieving optimal fit and proper alignment with the shooter’s eye. A well-fitted shotgun improves accuracy, reduces felt recoil, and enhances overall shooting comfort. Historically, gun fit was achieved through extensive and often expensive custom stock work. These kits provide a more accessible and adjustable alternative, allowing shooters to fine-tune their shotgun’s fit to their specific physique and shooting style. This adjustability is beneficial for improving performance in activities such as trap, skeet, sporting clays, and hunting.
