I have edited this first post to help those that find this thread.
We are building up differing versions of the Evil-M, a stacked tube version of the Viking that was never released by AKALMP.
Here are the current bits of important information if you want to follow along/mimic.

You can use a Merlin extrusion purchased from AirSoldierProducts.

Purchased new from AKALMP
Purchased from AirSoldierProducts, comes with gasket.
Will have to be built or modified from an existing frame.
Distance between screw holes is 5.25.
