I have everything just waiting on some small pieces that have already been shipped. I already came well prepared with a lower, parts kit, built upper and BCG and CH. Magazines and lots of them and of course ammo!Hope you can find parts at reasonable prices, I have been watching Gunbroker and have been really surprised at the prices things are going for. Stripped lower that normally costs $90 are going for $250. Lower parts kits are also selling out very quickly.
I am currently building my own custom MagPul AR and I have $930 invested including a scope. See my build here: http://rugerforum.net/projects/65571-superior-arms-custom-s-15-build.html
