Hello all, i had a hankerin to waste $58.00 so i ordered a eotech 552 clone from Dlgate. When it arrived[took at least 2-weeks] i opened the box[ it was packed nicely].All the Eotech logo was spelled correctly and it looked quite nice.I installed the two AA supplied batteries, it has a 65MOA circle and three small 1MOA dots, the 1 MOA dots are very sharp, i took it to the range and in sunlight the dots are totally useless. I decided to install top of the line lithium batteries and to my suprise this cured the problem. Well after about 3 weeks and about 1500 rounds down range it still holds zero. Would i put this on my M&P15,NO, but for my 15/22 so far so good, pghrich.
