I thought about doing that route with an MP5K last fall but I heard from a Maryland NFA dealer that MDSP wouldn't allow it to go through because they were calling it a copy-cat of the banned MP5K. Last I heard it was still going through the court system. I would check with an NFA gun shop on...
I have a pre-October 2013 Adcor, 16in DI and love it! FYI I did have the gas block come loose after a couple hundred rounds, that sucked but still a great gun.

Had them rebuild a 1971 Chevy 12 bolt posi rear a few years back, seemed like nice guys, work was good. :)
Just an FYI in case anyone else is interested, I called Sig Sauer yesterday and the rep told me that more news will be available at the end of this summer about the .40 and .357 cal conversion kits for the sig MPX, so basically they are pushing it out further and further :envy::tdown:
I heard recently that MDSP is considering an AOW to be a copycat of the pistol. I am going to try my luck with the sbr route since I currently have an uzi rifle.
I would be interested if a suppressor could be pinned on but from looking most 9mm suppressors are 7-8 inches long. 20oal + 8in < 29in evil rule :(
May just get the pistol version then a small can for her down the road.
