Glad I listened to suggestions to get the 2.5x ACSS. Got it mounted and some rounds down range over the weekend. I just hand tightened the mount so it did loosen up some (the instructions clearly state how to mount and tighten it, I was just in a rush to try it out). I shot it with and without illumination. I believe this optic is going to suit my needs just fine although I will order the ADM mount which was out of stock when I purchased the optic, just like the idea of a QR mount. All my shots were made prone from the back of my truck using a backpack as a rest so sometimes the fore end was resting and sometimes the barrel ... I just wanted to shoot and get the optic roughly dialed in. Will go back another day and be more disciplined and thorough.
Thank you Primary Arms!
