Up for sale is a ACOG 4x32JN8:12 made for the M4a1. It has the doctor optic red dot and the fiber optic bar. I have only used this sight twice at the range and the rest of the time it has been sitting in my safe, It looks brand new no scratches at all, I dont abuse my stuff. I believe I paid about 1500.00 for it a couple months ago. Price is $850.00 with free shipping. I will only except PAYPAL and payment must be made within 24 hours. The best way to get a hold of me is through email.
