Benelli mag extension tube

[sernv99]

just got a Benelli M2 tactical, 18.5" barrel.

what's the largest capacity for a mag extension tube do I need to have it sit flush with the barrel?

what brand is reliable? some suggestions from others have said SRM from Brownells and Dave Metal Works. Anyone else have opinion on either one or others?

Ive got the sure cycle 6 shot extension for my SBE. Once I had the collar ring adjusted its a blast. I keep it on during the off season, with a empty shell of lead at the muzzle end of the tube, in front on the spring. It helps me swing smoother with a lighter gun Less jumpy
