Not really. I have several friends that done with AR22 conversions. Looks cool. Fun to shoot. And super cheap ammo. The paperwork is easy, especially since I already have a corporation. Before I buy a swat pistol, I'd like to know if it will drop in. The know the smith M&P works like that as I saw someone at a gun store do it. I'm buying a suppressor for my my AR anyway (it will work on the 22), so why not short barrel it?
Will the 522 pistol upper pop right on to a 522 rifle lower? Thought this would be a fun suppressed shorty. With the appropriate paperwork of course...
