This is a far better scope than the price would indicate. The eye relief is perfect for use on a compstock using a 0 moa extended weaver rail with the scope mounted all the way forward. It allows plenty of room to compensate for stock compression during recoil and provides the added advantage of being able to shoot a scoped rifle with both eyes open making game aquisition much easier at higher magnifications. I have it mounted on a rem 700 bdl in 300 win mag and have another on order for my 7mm. I ran 30 round through the 300 in rapid succession at 200 yards with a group aveage of 4 inches. This was the 3rd scope I had purchased for this rifle, and thus far it has performed well above expectations
