Thanks for the responses!
I checked the pin before I started tapping. If I put the rear take down pin in first it goes in with no problem, but then the front pin wont go in.
So this tells me that the pins and holes are all the right size (front and back), but one of them will have to be tapped in.
I could get the rear take down pin started (very little bit) but I couldnt push it in by hand. Yes I had to tap the pin pretty good to get it in...I didn't pound it by any means..but I did tap it pretty good. It seemed like It was a little easier the second time after firing the weapon.
Does this mean that I can only use this upper with this lower, because of possible stressing to the upper/lower?
Is stressing out of spec. possible? If it is, which will it happen to...the upper or the lower, or both?
I don't know, I guess since this is my first AR, I'm kind of worried and I have no clue if this is normal with brand new lowers.
