Hey folks, Im still green at this, but I THINK I may have bought a defective red dot scope. I ordered this thing.. http://www.midwayusa.com/viewProduct/default.aspx?productNumber=185489 It arrived this morning and I mounted it immediately. After looking through it casually, I noticed it seems to be off center. Not the dot, but the whole tube assembly. It feels like the whole tube is aimed up and to the right. The dot position seems ok I guess, but the whole thing is all catty-whompous Should the front iron sight really be down in the bottom left corner of the view area in the tube? Also, what is that black notch piece in the upper right of the front lens? Thanks for any info. I have no idea whats going on here. If it's normal, it's weird!
