This is a Comp M with a 3MOA dot. I purchased this from the EE and just refinished it with Alumahyde II. It had/has some cosmetic issues, but this aimpoint has seen combat. It is in perfect working order because it just came back from Aimpoint.
I'm also throwing in a free cap strap and kill flash, which sell for 35.00 and the battery is brand new.
Like I said, this aimpoint has seen combat before and there are some cosmetic issues, but the glass is perfect.
