Well was in a LGS and picked up a Lower parts kit for 49 bucks. So I guess I gotta get a lower to put them in. They are so lonely sitting in their little colored bags. Anderson Manufacturing outta Hebron, KY. The lowers go for 49 also. a full 5.56 upper with gas is 250. So the only thing missing would be BCG and Stock. so a full build for under 600.00 that way. Or I have an M4 profile barrel. could get an upper for 50 all the rest for about 150.00 so 300 or so with parts I have already. Hmmmmm. Wonder what I should do.
