I see Masterpiece Arms offers a MAC style carbine in 460 Rowland with a complete 45ACP upper for less than $1000.00.

Has anyone here tested this piece.

It is a bit heavy, but less than a Thompson.

I love my 460 Rowland S&W Revolver, and my 45ACP's. This might make for a nice companion carbine.

Maybe the non response is the answer to the other thread on is tactical dead.
