Shotgun is mostly used on short distances, that is why you can see red dot or holographic non-magnifying sight on a shotgun more often than optic sight. Typically, red dot, reflex and holographic sights are designed for fast target acquisition usually within a 100-yard range, which is suitable for both hunting and tactical situations. Many shooting experts recommend that you shoot with both eyes open especially in a tactical situation. Red dot sights allow shooters to keep both eyes open because of the dedicated focusing of the sight. The shooting eye is not strained when using the sight.
First rule of home defense: “If you can’t identify a target you can’t shoot it”.
That is extremely important because you must not shoot a target that you can’t see and identify. If you hear something downstairs during the night you need to check what it is (of course, calling Police first is a wise idea).
Eotech Shotgun Integrated Forend Light for Remington 870: Installation, Review, Advantages, Disadvantages
I think that two best new products of the 2012 were: Eotech Integrated Forend Light and Magpul Stock/Forend.
They are very good and affordable upgrades for Remington 870 shotgun.
Eotech shotgun integrated forend light for Remington 870 is available for ordering. It looks great and I really like it. It would be interesting to order and test one or even compare Surefire and Eotech forends.
Strapy has posted very nice pics of the Remington 870 he has built for his wife. Very nice setup.
