I have one that I just put together. It has the following parts:
Daniel Defense upper receiver
Model 1 Sales 10.5" barrel -- with matching bolt only, no BCG
Low-profile gas block
Midwest Industries free-float forend (carbine-length)
No charging handle
The barrel and bolt have a small number (less than 200) of rounds through it. Everything else is brand-new and never shot or assembled before. Please PM me if you're interested.
