Holosun 407c 2 moa red on a truglo rib mount way out on muzzle end of a 28” barrel. And a Holosun EPS with green mrs reticle on the cut out at back end of receiver of new Mossberg 940 pro.
The red flares pretty bad for me but no issues with 2 moa way out on end of a long shotgun it’s still small enough dot even flared. Fov is not a thing with this mounting position, there is no fov really. You have a dot inside a really big black square ring so to speak.
The green mrs on the mossberg is amazing, and the full size window of the EPS (not compact ‘carry’ model) means fov is a thing but being so close to your face it’s huge bright fov and very easy to find and keep dot. The green mrs reticl in this location gives me no astigmatism flare, and prefer the 32 moa circle only as thats 16” at 50 or 8” at 25 but it’s a buckshot slugs set up...for a bird set up I’d probably switch the reticle to the dot only? Maybe not? The circle is a great representation of the pattern so it would need experimenting without on some clays to decide.
They are both solar and can be run without their batteries but do have battery for night duty etc. Plus shake awake and manual modes etc. Holosun is some top gear. Small and lightweight, worry free eith solar.
