5 years old, I'm replacing it with a BEAST. It was installed on a target/varmint rifle that was taken out about 3-4 times a year, so there is no visible wear. It was installed torqued to exact torque specs in hand lapped Bader Ordnance rings. The glass is perfect and the scope is in excellent condition, see photos. Comes with original box and paperwork and I will include the original sales invoice from Bruno Shooter's Supply for your records. It does not have Zero Stop (you can make a ZS with a $0.50 nylon washer from Lowes and 30 minutes of your time - this is what I did) or the high speed turrets (none did 5 years ago). $1449 shipped to CONUS. This is in my opinion the best value and quality scope you can buy. Ask the 50 BMG shooters. Thanks for looking. SOA please email me at email@example.com since I don't check my email on the site very often.
