What should I stay away from? this is somewhat of a budget build but I don't want to sacrifice quality and be unhappy with what I build. lower: Spikes stripped lower rec spikes lower parts kit Magpul Carbine Stock dark earth DSA complete buffer tube kit Magpul MIAD mission adaptable grip dark earth Magpul PMAG Magazine dark earth Tools: Roll pin starter punch set Complete upper: (really need input on this side of things) found this one *Surplus Ammo & Arms Complete AR-15 M4 16" Upper Receiver 5.56 1:9 - Surplus Ammo but not sure if this is a decent upper or not. Thanks in advance! This site is incredibly helpful and informative!
