I have this site on a S&W M&P 15 22LR, not a high power rifle, or a assault rifle like a 7.62 or 5.56 just a little 22 assault style rifle. After sighting in at 100' it puts anything closer off mark, no biggie easy to compensate, but after 15-20 rounds it is off again, it will stay on peper but 3" groups at 100' I can do better with the iron sites. Use this for the kid toys and Bb guns, but dont waste money on ammo putting it on a real gun. (or rifle)
Pros: CHEAP, Literally and figuratively
Cons: Battery drains way too fast, constant adjustment to zero in.
