I have a 24” M5 Aero Precision upper chambered in 6.5 Creedmoor with a black nitride bolt carrier group and a warhammer extended charging handle. Upper has fired less than 1 box through it. I decided to go a different route for my AR-10. This upper only has maybe 20 rounds through it. I’m asking $700obo. Will consider trades that catch my eye, even if I need to add a little on my end.
