Bought this Vortex Optics Sparc II Red Dot Sight - 2 MOA for my 2nd Gen Sport about three are four years ago and it has been stellar at the range, if I remember right I paid about 160 bucks for it, money well spent!:)
Let me put it as you simply as I can, first of all I have put a lot more into my first Gen than you.
Second I see no reason for me to sell it since I like what I did to it and I am satisfied with it's performance and looks.
Thirdly I will never in my life time get what I put in to it, so...
I have a later M&P Sport and it was a good color match on the upper and the lower when I purchased it, to be honest I looked at it before I even bought it.
In my opinion this totally unacceptable since this should of been rectified through Quality Control before the AR went in the box and out...
There is a lot of good choices out there, do your research as you are doing here on this forum and you will find the one that fits your needs. My choice was the Raptor. :)
Did the same with my old generation Sport. The only thing that is still part of the Sport is the lower, barrel and buffer tube. What can I say I got bit by the AR Gods. :eek:
