I just received the Primary Arms M3 clone today. I was hesitant after having a Chinese copy go tits up the second range trip. But the reviews looked good.
I am again impressed with the quality and features from a product PA carries.
I have not shot it but I don't look for there to be an issue.
The dot is actually clearer than my aimpoint.
Thanks again Marshall for providing a decent, inexpensive product to us.
