Looks like there are parts for at least 3 new builds over the Winter.
Now making the decisions on what to build and which barrels to use.
Seems the barrel choice would be first and then receivers whether standard, XM21 or M21 would be second.

Barrels hanging out in shop from top to bottom.
Leaning toward using 6 - 7 - 8 at the moment as these have proven to be excellent barrels.
