i bought a psa-m4-orc a few weeks ago. before i bought it from my dealer i called psa up 2x to get the specification's of the gun. each time i called they said it itwas the same exact rifle as the premium and that it comes with a MP tested bolt. after i picked the gun up i got it home and noticed the bold was not MP tested. so i post on ar15 (http://www.ar15.com/forums/t_2_301/238373_question_about_psa_m4_orc.html) and call them up. they than say that its the right BCG but they will send me out one that is marked. so after waiting for 2 + weeks i finally have a gun that i can shoot. I took it out to the range for the first time this past weekend and put 80 rounds through it. when i got it home i took it apart to clean it and saw a huge scrape/gouge on the inside of the upper. this is the first rifle i have owned and am not sure if this is normal and part of the break in period or if this is something to be concerned about as i dont want the exposed aluminum to start to corrode overtime. please give me some input guys
