Alright this is cross posted on ODT as well as Arms List. Its a mixed parts AR. Unknown flat top upper/barrel Chambered for 5.56 Anderson Arms Lower CMMG LPK Magpul Polymer sights MOE stock MOE BLK grip UTG pro free float quad rail Minor wear on birdcage flash hider and ejection port area on the upper reciever. Odds are the guy didnt have a table vise or proper tools to work on it, Ive seen that kind of wear before. Both DO NOT alter the function of the rifle. The rifle funtions flawlessly.
