I am thinking of switching over to 5.56. This is my armalite 6.8 all factory gun. The front site has been changed to a folding site, comes with 30 rd Barrett magazine and the factory 10 rd mag. Also have 70 rds of ammo. Previous owner shot it around 30 rounds and I have not shot it yet. I am looking to trade for a factory 5.56 (prefer a colt 6920 in like shape). I am in Monroe nc and would prefer ftf around this area thanks.
