So, I am going to start to gather parts for my build. I have a few questions about it though and hopefully everyone can point me in the right directions. I am going to pick up a simple stripped lower probably spikes from somewhere when they have a nice sale going on. I was looking at the slide fire stocks but I am not currently sold on them just yet. They would be fun to have but its a lot of wasted ammo and money by the time you are done with it. I am looking for a good quality upper that is already build though. I don't have the tools or knowledge to put one together just yet. I keep watching the sales sales sales thread so I can find some nice deals on lowers and uppers and sights and whatever else I am going to need. Keep up the good work. Thanks. Questions: 1. Is spikes a good quality stripped lower? 2. What is a good quality assembled upper to be watching for sales for? 3. Any suggestions on a nice trigger for an ar? 4. Red dot with magnifier or a scope? 5. What is the whole debate on milspec and commercial? I saw people having issues with having their gun with milspec parts and the sight was off or something. I see that milspec is forged but then you have to buy all milspec parts (like stock and rails?) when using milspec tube?
