Ok so I am looking to do a cheap build and this will be my first ar. When I say cheap I mean the perfect balance between inexpensive but good quality products, not just all shitty cheap stuff. I could take some shitty parts because I plan on upgrading the gun slowly to all great quality parts and parts I know i will want once I get an ar and know what I want out of an ar. I am confused as to why people build because when I add up all the stuff I need to buy I could just buy a complete dmps for the money. So am I doing something wrong or does building actually cost as much as buying a complete rifle? I have watched the brownels videos on how to build one but are there and other sources you guys suggest I check out to find cheap, good parts? Thanks for the help.
