shipped or trade for Nikon or Leupold mildot scope. Prefer postal money order, but I'll take paypal (add 3%). I can take some pics, but it will take me a day or two. If you can't wait, look here: M4 upper
This upper is literally brand new. It hasn't left my safe since I bought it.
EDITED TO ADD: Am also interested in Burris FF II and Bushnell Elite 4200. I'm looking for something in the 4-16x range with mildot and target turrets.
