WV Hunter,
I suppose its been about 9 years ago I purchased a 3x9x42 AR scope and have used it on my TC Encore ML. It is a good scope and it works very well. The only issue that I have with mine is the outer portion of the reticle seems to distort the image a little, but I can't complain as I paid $69.00 for it and never intended to actually keep it. The actual cause of the issue may be my eyes rather than the scope. It serves its purpose and I could have shelled out more money, but if it ain't broke don't fix it is my motto. If I had the money I would switch everything over to redfield/Leupold but I am satisfied with what I have for the moment. They are a good scope especially for the price.
