I wanted a 5x36 for my AR Platform and could not justify the $$$$ for an ACOG. This is a poor mans ACOG and I am pleasantly surprised by the quality and ruggedness of this scope. Love the illuminated Red, Green reticle as it makes this a fast acquisition optic. Also there is an option to set to Black as to not use battery. Also includes flip up dust covers and pica tinny rails so you can add other accessories. Very pleased with this purchase and I would highly recommend this scope!!!
