So I was really excited about my primary arms purchase M4 red dot optic. I get it in and mount it to my quad rail on my ak. 1st time out I get it close to sighted in ran out of time. Second time out I could not get it zeroed in to save my life, then all of a sudden it cut off on me. I thought maybe the battery is no good so I put a new battery in and nothing. So I email PA and they are great and immediately send me another out with return shipping label (awsome) they guy at PA also told me I should take the spacer off so it won't sit so high on my ak and sent me shorter allen head bolts. I thought that was nice of him. Get the sight and its setup with the spacer and has two short bolts in the box. So i take the spacer off and the go mount the M4 to the mount with the supplied bolts and it 1 of the two bolts wont tighten i look at the threads and the first two threads are stripped i guess overtighten from the factory. Frustrating but i know stuff happens. So I email PA and they tell me at this point send them both back and they would give me a full refund. As if i am being difficult. I told them i don't want a refund I want a working optic for my AK. Im frustrated they act as if i am being difficult when I feel I have been pretty understanding considering the circumstances what do you think?
