M5 LONG

To load the gun, shells are fed into the bottom of the action, where they are pushed into the tubular magazine. Most A-5s have removable plugs in the magazine which prevent more than three shells from being loaded (two in the magazine, plus one in the chamber) to comply with US federal migratory waterfowl laws, as well as some state hunting regulations. With the plug removed, the total capacity is five rounds. If the chamber is open (the operating handle is drawn back) the first shell loaded into the magazine tube will go directly into the chamber (there is a manual bolt closing button under the ejection port), the bolt then closes, and all further shells fed into the gun go into the magazine.
