The Burris AR-332 Tactical Prism Sight is a compact, rugged, and waterproof CQB scope that's worth serious consideration. It features a great Close Quarters Battle Reticle (illuminated Red or Green with variable intensities) that has the added benefit of built in ballistic compensation hold marks for point of impact out to 500 yards. It comes complete with integrated lens covers, carry handle mount, and a Picatinny Rail Mounting System.
