So CD and I took a Gen 4 IOR 3.5-18x50 FFP and a IOR 6-24x56 FFP scope and compared them to a NF 5-5-22x56 NXS and a S&B 5-25x56 PMII. The IOR compared to the NF had glass that was brighter and defined objects more clearly. This was noticeable from the lowest to highest magnifications. The IOR compared to the S&B was abit less bright than the S&B,but was equal in the definition of objects. Again.through out the magnification range. The jury is still out on the IOR rings supplied with the scope that are quick release. They look like they will do the job. Time will tell. The Turrets have a very positive 1/10mil tactile click. They have a built in zero stop as well as an extra pointer that works as an adjustable secondary zero for another range or caliber. The on/off illumoination buttons are very nice and feature an auto off as well.The reticle was very easy to use and out at 600 yards the center dot was barely visible. Nice when shooting P Dogs. Overall,it is a beefy scope that has some great features not found on scopes that cost $1000 more. The S&B in my opinion is still superior,but dollar for dollar the IOR is a better value. FFP,Zero Stop,Rings,35mm Tubes,Lifetime Guarantee,Secondary Elevation Selection makes for a good deal in my opinion. Try one,I don't think you'll be sorry.
