Three Shot Magazine Adapter

The A-500G shotgun is delivered with the three-shot magazine adapter installed in the magazine, limiting magazine capacity to two shells — allowing three shots total in compliance with federal migratory bird regulations. If you do not wish to be limited to three shots — when it is not required by law — you can remove or reinstall the three-shot adapter (plug) as follows:

3. Release the breechblock forward slowly by pressing the breechblock release button and slowly allowing the breechblock to travel forward. Do this by pressing the button with one hand and offering resistance on the operating handle with the other hand, gently easing it forward to the fully forward position,

4. Full back approximately 1/4" of an inch on the operating handle. With your other hand: insert two 2 3/4" (or two 3-inch magnum shells) into the magazine if you are it removing the three-shot adapter OR insert four 2 3/4" shells (or three 3-inch magnums) if the three-shot adapter was removed previously and you are it reinstalling it. Position an additional shells as if you were going to insert it into the magazine (it will stop only partially inserted because of the full magazine).

5. Apply steady, hard pressure on the shell, pushing all the shells forward in the magazine until the magazine spring retainer is dislodged from its compressed fitting at the end of the magazine (See Figure 16). You will feel forward movement of the shells in the magazine when it is dislodged.
