This is a brand new ( bought as a complete firearm) DDM4 7P 300 blackout upper with a 10.3 inch barrel. This hasn't been fired or even takin apart to be lubed yet.

I did install a CAT AI nano muzzle device but can take that off if wanted. Also includes the original flash hider muzzle device from factory.

Here is a link to the firearm and it's specs:
