I've been lingering here for a while and thought I would create an account and post up a question for everyone. I've decided to turn my Remington 870 Marine Magnum in to my HD weapon of choice. I've already made a few upgrades including the Knoxx collapsible stock, side saddle, and Houge rubber forend. The shotgun only comes with a front bead for a sight and neither the barrel or receiver are tapped for iron sights. I don't have anyone locally who I would trust to work on any firearm I own so I thought I would take a different route. I bought a Black Aces Picatinny Rail for it and I'm currently waiting for it to be delivered. I thought about using rail mounted BUIS as the primary weapon sights, but by the time I buy decent sights I'm looking at $250 and thought maybe I should just go with a reflex sight. Ideally I would like an Eotech, but if the wife finds out I spent $500 on a sight that I hopefully never need to use, she would feel like she has to drop $500 on new clothes.
I guess what I'm asking is...... are BUIS worth considering on an HD shotgun? If so what would you recommend? Should I go with a red dot/reflex type of sight and should I invest in an Eotech (or something of similar quality) or can I find something quality for under $200?
