I have an old Army buddy that is willing to sell me a Colt AR for 400 bucks, but I don't know if it is a good deal or not. I would like to pick something up and trick it out little. I am including his description of the rifle below. Please chime in and let me know what you think.
"I have an AR15A2 Sporter (it is an M16A2 with an A1 rear sight) with a 1/7 twist M16A2 Barrel that I will trade to you. It
is a genuine Colt with a couple of cosmetic issues (no Performance Issues - shoots perfect).
It has a spot about the size of a dime on the upper receiver that looks like some kind of Acid got on it and ate the finish, then just below
that on the lower receiver is a spot about the size of a quarter where the finish is bubbled up, it must have been laid on something that did
it. Whatever did it is done and it has not done anything more since 89".
