I used a SJ hardware extension on it. I got the +3 and I used the plug that came with the gun to block it so only allow 6.8 shells into the gun. I think the tube you need is for a Benelli nova as it's the same threads. I got the +3 so I could compete in the USA with their max of 8 shells in the tube.
The Sj +2 will make it so you don't have to plug the gun.
