Just so everybody knows, I got the 3-9x40 mildot a while back and put it through its paces and it passed with flying colors. Box test was perfect, the adjustments are precise and perfectly repeatable and it returns to zero every time. I leveled it up on the rifle and it tracks a perfect vertical and horizontal line. The mildots are perfectly accurate. These scopes cannot be beat for this price, the clarity is sharp edge to edge. Its basically Mark 4 quality in a very simple package. 1" tube instead of 30mm, T1 and T2 knobs instead of M1 M2 and M3 knobs, fixed parallex instead of adjustable ( unless you get the 6-18 model and it has an A/O), They are even tested to the same standards as the Mark 4. I recommend this scope to anybody who can afford the Mark 4 but want the Mark 4 quality and durability.
