I’m looking for a 10.3” DD barrel. Preferably with .07 gas port / pinned gas block if possible

I have the following parts I can trade.

Magpul UBR gen 1
LaRue Tactical MBT-2S Straight Bow Trigger
Rosco 13.7” barrel- 0 rounds through it

If interested in anything let me know, and we can work something out
