The Mossberg 930 platform has provided a lot of opportunities for companies to manufacture products to improve the functionality, and reliability of the shotgun. Pretty much every area has been addressed except the heart of the shotgun which is the gas system. That will all change soon.
We have just released a Plus One magazine cap to increase the capacity of any shotgun with a Nordic MXT magazine extension by one shell. This is great for 3-gun competitors, and Tactical shooters looking for an edge over the competition.
