:x :x :x It seems I can do nothing right today. I was planning on taking my new Stag AR-15 out to the range this weekend, but it seems I failed to reinstall the stock properly after slapping on a single point sling mount. This caused the buffer tube spring and retainer to go tumbling into the lower and get all bent to hell when I tried chambering one. I got pissed off, and in my haste I bent the take down pivot pin detent spring and (of course) lost the pin. :x I think i need to leave this gun be for the rest of the day and see what I can do tomorrow about getting replacement parts. Moral of the story: take your time and do everything right the first time.
