Hello all, I'm a US Army infantryman currently stationed in Ga. I'm about to embark on my first AR building journey and obviousley have many questions. A friend of mine bought a number of stripped lower recievers from PSA and the price was right so I jumped on one. It arrived today. Its something I have wanted to do for some time now, but do to deployments, moving duty stations, and starting a family have not gad the means until recently. I am very familier with the M-4/M-16 series rifles so I have a decent level of knowledge as far as gun-theory and operation/maintenance but as I stated, have never built one from the ground up. What I am looking for is advice on building a decent rifle at a moderate price. Nothing fancy, just a 16 inch flat top. I'm also interested to hear about peoples mistakes and common first timer pit falls. I don't know what I don't know, so I can't ask a lot of specific questions. Thank you all for any advice you can give a grunt and first time builder.
