Geez! that is a huge aperture!!! I have bigger ones but nothing that big! I did not really like the big ones so I stayed with this size. Although my NECG has one a little larger...
You can see the larger one that I have use here...
I also use a larger diameter peep hole for hunting to gather more light - early in the morning or into the evening. you can see the oversized peep hole in this pic.
