1: Larue Tactical Iron Dot Fastfire it's in excellent shape like new. I bought it thinking I could mount it on my Ruger Mark III but it only mounts on Picatinny type rails. Below is the description from Larue's website. Asking $315 shipped
Originally developed for semi-automatic handguns as a sight that could withstand the abuse of slide mounting, this tiny but tough, non-magnifying, reflex type red dot sight has proven to be a terrific fast target acquisition sight for turkey shotguns, deer slug guns, tactical and close range hunting carbines, muzzleloaders, paintball guns, home defense shotguns and even upland and waterfowl shotguns.
FastFire weighs in at just 2 ounces, fully mounted, and with its all-metal housing construction and advanced circuitry, the FastFire sight is extremely robust, shrugging off recoil forces up to 1000 G's.
A target-directed light sensor automatically adjusts and controls the brightness of the 4MOA red dot for maximum visibility based on the ambient light conditions - from very dim in dark conditions to very bright in sunlight.
With unlimited eye relief, the FastFire can be used on both handguns, rifles and shotguns and its low magnification provides an extremely large field-of-view and the ability to aim with both eyes open.
Fastfire's multicoating is sandwiched between two highly polished, optical quality glass lenses for protection from scratches and abrasion for a bright, clear sight picture. FastFire is parallax-free at 50 yards.
Although FastFire has an On/Off switch, simply replacing the protective cover activates the built-in Battery Saver mode which allows the battery to last up to 5 years yet always be instantly ready for deployment by simply removing the cover. Power is provided by a supplied standard lithium Type CR 2032 3-volt battery
