I love the ACOG 4x32. I use the USMC version which can be bought. I don't own it, the Marine Corps just uses them. I fired with it for the 1st time on our range and raised my score from 311 expert to 335 expert with a max score of 350. This I shot my zero at the 100yrd, fired sitting, kneeling, standing at the 200yrd; sitting and prone at the 300yrd; and prone at the 500yrd. Also they can really take a beating. I have seen these ACOGs go threw hell and back. Mine was beat to hell and still fired true. Also
The fiber optic really make a diifferance, but in bright light it is imperative that you take a piece of black duct tape and cover 6/8 of that fiber optic, or the cheveron will be to bright and creat a glowing haze around it which will make it appear bigger, this will make a hell of a differance between 100,200, and 300 yrds. Also be careful with adjustments, every 3 clicks is 1 inch, you also must smack it after making an adjustment. Overall very accurate and very quick. I even used it in my CQ box drills failure to Stop and all that at 25 yrds. Also always make sure 1 1/2 inch eye relief. Overall I give it 4 1/2 stars. And that's only cause I popped myself in the eye with it while firing.
