I agree with those who are saying the build is not that difficult. For my first build I bought a stripped Palmetto State Armory lower. It was such nice quality I thought I would ask what they could do to modify one of their complete uppers to meet my specs. They gave me a good price so I ordered. If you have some basic tools, basic mechanical know-how, and some patience you can put a lower together.
As far as it not being any cheaper than a complete rifle, I don't know that I agree with that statement. I put together a fairly tricked out rifle (MI free float quad rail, low profile gas block, flip up front/rear Magpul Gen 2 MBUS, Ergo grip, flat top upper, .223/5.56 stainless steel Wylde barrel, Magpul mil-spec CTR stock). With 15 magazines, transfer fee, and shipping it was just over $1,000. (see spreadsheet)
The one thing I would have done differently would be to get a better trigger.
Just take your time, read, watch videos, and ask questions. It is not that hard to do.
