It's...an AR. I selected parts for lighter weight and good quality, a billet lower with a bolt release on the right side, a failzero BCG and a 16" 1/7 proof carbon fiber barrel. I used a centurion rail and raptor charging handle and there's a Magpul ARCA rail on the rail. The barrel has 600 rounds through it but every other part is unfired. There are some scuffs in the cerakote from moving out here.
