I have 4, 3x15x50 (28 Nosler) , 2 - 4x20x50 (7 mm mags my sons guns) and a 5x25x50 (300 win mag) all with MAD knobs. All are very reliable, return to zero and track spot on. Shot my bull elk last year at 505 yards with the 5x25x50, then a mule at 100 yards, then the guide shot a coyote at 250 yards, then another hunter dialed it to 600 for a follow up shot as his Vortex scope wasn't tracking. All shots were spot on and returned to 0. Took me a little while to get use to the FFP but now I really like it. All the scopes have Burris custom yardage turrets and are dialed in!!!!!
I was really impressed with the glass. I have a swarovski, leupold, 3 bushnell, zeiss and a sightron scope. The Burris's have the best eye relief, eye box, and main scope body length, gives me alot of room to mount my scope as far back as possible. We used my scope in really low light to compare to my Maven binocs sizing up some mule deer. Very impressive!!!! The Zeiss were about the same glass. the Swaro's have great glass but a horrible eye box.
And they won't break the bank.
