Ok, I have never built an AR before, just bought a lower and so here goes. My plan is to do it as cheap as possible but with parts that are decent, but as inexpensive as possible. My thoughts are that a rifle would be cheaper than a pistol, mainly considering the cost of the Sig brace, but correct me if I am wrong. I like Magpul furniture, and am thinking of going all FDE to keep it simple to differentiate between this one and my 556. I want to start it off with iron sights and want a dependable set of those. But definitely plan to put a 1-4 power scope on it eventually. Any and all suggestions would be great. Links to places to buy parts or your suggestions for decent triggers worth spending a hair more for etc are great! Thanks
