Consider a red dot. I really like the products from Lucid (not a sponsor). Their products that I have handled are excellent and very reasonably prices. I have an HD-7 on my Tavor.
Obviously, the Aimpoint Minis are the state of the art. You pay lot for the state of the art, though. (sponsor)
MTAC from Burris (a sponsor, BTW)…I have 2, and they are some of the finest scopes I've worked with. Their 1-4x is one of my workhorses, and the 1.5-6X will be on my 3-gun JP/Ruger this season.
Not a sponsor, but good friends, Leupold's Mark AR MOD 1.5-4X illuminated is an incredible value scope. I used it last week on my JP 9mm in the local carbine match. I was the only shooter to shoot clean.
