Product review (3 stars): Glass broke after 40 shots
I am really reluctant to give negative reviews on things  I buy after thorough research. But I have to give it a 3 star as it really disappointed me. The glass on viewer side just shattered after 40 rounds of 7.62x39 normal FMJ ammo on my SKS. It looks like that the nob inside the tube at 4:30 location caused the shatter. No direct contact from anything, it just broke like that. Does it hold zero? I didn't even had a chance to see.
