Dan, why not just cut a piece of blank to look like the front of the Uzi, so MK9 screws right on? DPMS and most other tubes are 2" OD, same as AWC can. Make the barrel, mount it to the upper, screw on the can, measure the open gap, and cut tube to fit, leave maybe .005-.010" gap.... Sound like a plan?
[blue]Looks like front of Uzi, barrel is 8.5" same as MP5, and OAL is same as Uzi w/MK9, more grip friendly though--[/blue]

[blue]AWC MK9 installed-- measure the gap from nut flat to can, cut the tube to fit with a small gap for expansion if it happens-- [/blue]

Joe, what you charge to move the works back maybe 2.5"?
