Factory Daniel Defense MK18 10.3" upper
No BCG/CH
Does include a Daniel Defense muzzle break, but it needs to be timed still

This upper is unfired. I bought it new as stripped factory upper (no bcg/ch or muzzle device) put a ASR and BCG in it then decided to go a different direction. The muzzle break on it is off of another factory DD upper and is unfired as well. Like mentioned above, it does still need to be timed.

Mostly looking to sell but may consider trading for/towards the right P320, PCC, 308 bolt action, or IR laser

What does being timed mean ?
It's where you use shims, which are just washers of various thicknesses, to get the muzzle device to line up in a certain orientation. The one pictured below has ports that go out the sides so you have to add the right combination of shims for it to line up correctly, ie timing it.

The break on the upper listed probably isn't that big of a deal, but it does have a small notch in the front edge that DD always times to the bottom of the barrel. I honestly don't know if that serves any purpose of its just aesthetics.
