A while back I had discussed with someone on here the different options for building something like an M4-style rifle. He said you can build a nice high quality gun with different brand pieces on it for a rather low price. He actually sent me some links with receivers that were on sale at RRA and a few other websites. I'm looking at getting one again. Does anyone have any sites they frequent that has higher quality parts for decent prices? Or whole guns for that matter I guess. I think the one we had pieced together came to about ~$700 or so.
