The Benelli M4/M1014 Titanium 7rd Magazine Tube is a high-quality accessory designed for Benelli shotguns. Made from lightweight and durable titanium, this full-length mag tube is designed for 12 gauge ammunition.
If you have a Robar np3 H2O Benelli 11718 this is what you need. It’s a match in finish. It also looks exactly like the tube on the Benelli 11711. I used lots of heat and soaked the existing tube threads in Kroil overnight. The next morning the tube spun right off with little force.
