Been lurking arround a little, decided I'd join. A lot of good info here. Here's what I've got, and what I've done so far:
15-22 with flash hider, tapco rail covers, and some color added.
I've shot alot of guns, and I have to say, is is one of the most fun. I take my kids to the range, and we'll send 500 rounds down range. Good fun for everyone.
