@RRAMODERATOR
Steve, I ordered and received an A2 upper a month or so ago. Its missing the "a2 Rear Sight Index Screw". I unfortunately discovered this when I went to zero it yesterday and the rear sight elevation barrels spun freely of one another... lol. no big deal, but i cant seem to find the part on your website to get one. I also don't have my original order number because i cleaned up my email and deleted a bunch of stuff I felt I no longer needed.
Any help sir?
