I would not waste your money! I have one and the thing needed to be disassembled to re solder a wire after 100 rounds! Its hard to change the battery, and it cannot be used with both eyes opened the sight picture is off. I had it on a Glock 35 and it would not hold point of aim after a couple of hundred rounds,shot bullets allover and gave a 6" group at 50 ft
. took the scope off and I had a 11\2" group!? I hand load and I have to use Lead indoors where I shoot so the sight did not take much abuse with recoil. Its built well enough but will not stand up to much abuse! I will put it on my Neotec, if it does not work out in the trash it will go!! maybe a Bushnell Holographic next.
