NIB, only had it a few days.
I bought it thinking it would work with the B&T 10266 MP5 mount for Aimpoint Micros but apparently the mount is slightly different from the T-1/T-2 mount and it didn't work out and I had to buy a T-2. I really prefer the M5 to the T-2 and had gotten out of T-2s but here I am and now I don't need this.
I took it out and removed the junk Alkaline battery and put in an Energizer lithium and then promptly realized it was not going to work so the optic is absolutely NIB.
Asking $750 shipped CONUS only, USPS MO, venmo or Zelle only.
