Nordic Components, the grandfather of shotgun tubes as well as many other gun parts has changed the game and offers the biggest variety of shotgun tubes. Everything from Plus 1 to Plus 9 rounds on over 30 different type shotguns. With a variety of lengths to choose from, many can benefit. They’re great for hunting (where allowed), home defense, breachers and competition shooters. I have literally ran the same tube for the last 4 years on different shotguns and have yet to have any problems with it. I change the spring every 800-1000 rounds and it keeps feeding.
