Hey Phil,
Haven't been able to get to the range yet with the new scope. i definitely plan on sighting in at 100 yards and maybe beyond if I feel adventurous.
It's an Osprey 4x16x50 Mil Dot. The mount is a UTG which will go away once my Burris PEPR comes in. The Burris is a nice mount, I've got one on my M&P 15.
