I tested one when they first came out. However, I did not put it on the scope checker, but I did the "square test" and it passed that with flying colors. I won the only match (300 yds) that I used the scope and it was very bright and tracked well. I was impressed with the quality of this offering.Anyone test the NF fixed power? Would imagine it has the same internal adjustment mechanism. Just wondered if anyone tested a couple yet.
