Traditional on-gun shell holder solutions require alterations to the shotgun. To make things simpler for users of Mesa's telescoping stock adapter systems, SureShell shotshell carriers are designed to be attached to the side mount points of the High-tube and Low-tube telescoping stock adapters. The push-button sling swivel mounting capability is still retained when a mounting point is used for a SureShell shotshell carrier, and a single telescoping stock adapter can accommodate multiple SureShell shotshell carriers at one time. The Adapter Mount Aluminum Eight-shot SureShell Carrier can only be installed on the left side of the receiver, unless it is turned around and installed alongside the stock. If installed alongside the receiver, you must use a tactical forend that does not overlap the receiver, or a factory forend that is cut down appropriately.
