AR10 Single Shot

Hello all!

I just recently put together the following components and the gun won’t eject and needs to be manually fed. DPMS LR-308 lower, Bushmaster upper, and Aero Precision barrel chambered in 6.5 Creedmoor. Not sure if I need an adjustable gas block or possibly there’s some incompatibility with the components. Thoughts and opinions please.

Hi. Please drop by the introduction section and tell us a bit about yourself.

What recoil spring and follower are you using.

Try and find the waterboarding thread and read that. That is the kind of info we need to help you fix your gun.
