I fell off the deep end and ordered the standard 20" oly kit by phone on Monday. I had it in my house on Friday. Only 5 days!! I assembled everything last night and took it to the range today for break-in. It functioned flawlessly and looks good too. The only gripe I have is that the handgaurd has alot of slop in it. Is this normal? I plan on putting a FF tube on it later, but this bugs me. The upper and lower fit perfectly with no slop whatsoever. I spent all day..fire, clean....fire, clean....fire, clean. I'm not finished beaking it in yet, but after 30 rnds. of blue box Black Hills 55g sp's, it's been hitting within 3" of poa @100yds(about 1-1/2 average). I know that is not spectacular, but I can't see much better than that with iron sights. I'm happy with it so far.
