Awesome sight!!! - Trijicon ACOG 4x32 Scope w/TA51 Mount

this sight is no doubt probably the best 4 power fiber optic sight on the market i love this sight but its not perfect a few things to be aware of before buying this sight #1 it doesn't have that great of eye relief only 1.5 inches this means if you like the stock on your ar-15 (if that's what its mounted on) fully extended your going to want the sight mounted as far back as possible leaving no room for BUIS (back up iron sights). #2 i have read this before on reviews and i experienced it my self this sight is hard to zero but is still very accurate when you get it sighted in. #3 if your looking at the green reticle its a good reticle but if you live in a northern climet like me when the grounds all coverd in snow and there's a cloud cover the green doesn't show up very good at all but during the summer months it works perfectly the reticle is stands out leaving no room for error so if you live somewhere where the ground gets covered with snow for 5 months out of the year i would recommend going with the fiber optic red reticle. and some of the ups if your looking for a indestructible accurate reliable sight your looking in the right place, the BAC (bindon aiming concept) is awesome it combines a magnified optic with a holographic sight just by looking through the sight with both eyes open for the holographic view and close your off eye for magnified view, and the sight is a little pricey but 100% worth the money, and you have the added benefit and reliability of no battery's and still having a illuminated reticle, overall i highly recommend this product. thank you for reading
