psa is good to go, they also have a m4 build kit for $599.00 add one of their blemished lowers ( I have several of them and they all came with no noticeable "blemishes" ) and you have an ar for around $750.00 after shipping and transfer, and 15 minutes of work putting it together. my only warning is they take a while to ship sometimes up to 2 weeks, if you do order a lower from them make sure you get your ffl copy to them with your order # written on it asap, they will not move forward on your order at all until they get it in hand. below are pics of some of my psa builds.









and a psa upper on a mag fde lower with another psa lower and build kit I just got this week for my next one.
