Absolutely love it. Have tried multiple ACOGs, and the 3.5 is the way to go. Amazing eye relief, and not much weight compared to the 4X... But the eye relief difference is massive. Very happy with it.
Perfect fit, perfect alignment. Pairing NVG with the sidekick 640 is absolutely awesome, and with the great FOV of the sidekick I'm able to easily navigate and merge the two in my brain. Works like a charm!
Excellent optic! unfortunately eye relief is too short for using properly with my helmet and ear pro, and NVG with piggyback RMR, so will go with the 3.5x. I've used both, and the weight is almost the same in real terms...I like the size of the 4x better, as it is smaller, but the eye relief is a massive difference for only using 0.5x in magnification.
Love it. I tried getting the Amber Dot, but I had to return it in favor of a green dot. I had a really hard time picking up the Amber Dot looking at mixed wooden environment. Green Dot is so much faster and easier to pick up. This thing is built like a tank and works perfect.
Excellent trigger, well worth the $100 black friday deal. I bought 2 of them, put one on AR10 and one on AR15. Would recommend, definitely increased the accuracy at distance.
Extremely well machined slide. Looks great on my 43x. I recommend it and would buy again. I paid low 200s for it and feel like it was a good deal. I don't know if I would pay 400+ for a slide though, at full price.
