I toyed with the idea of making a different design altogether, more straight out without the 3 large circles machined into it. But in the end, I find benellis cap design quite beautiful so decided to keep the classic look of the cap even though I probably could have achieved 1/4” to 1/2” more spring space.
The light mount is Southern engineered...I used a Toni System tactical barrel clamp with a pic rail section, then added a M-lok adapter. It's the best I could come up with to use M-lok. It places the switch right directly in front of my thumb, is pretty solid, and works, so I'm happy with it so far.
The Scalarworks RMR mount gives me co-witness with the iron sights.
