Hey guys, thought I'd share my experience buying a knock-on trijicon ACOG from wish.com... I paid $160ish for the model with the red dot attached. It took 5 days to arrive. Construction seemed very solid and it attached perfectly to my ACR. Ordered two months ago and finally got a chance to test out on some land. Only tested a few clips @ 150ish yards since I didn't have any hearing protection. My shaky ass was able to consistently peg a 5 gallon bucket while standing. While I probably wouldn't trust my life with it, at 1/10th the price, I think it was a good buy just for some target practice fun.
