I'm just really at a loss on why you won't register the lower.

you should do it and post proper video and pics of the project.

Do it.. you can be the test case to make it A-OK.  You can start the new trend!

Not sure why you are all bagging on the guy all GD style. It was a reasonable question and has been answered reasonably by those who have the experience to know.

With that said about 8 or 10 years back I found myself with a spare AAC Ranger II and an extra 6933 upper. I was seriously considering having the can welded to the upper to have a gun that I could carry to other states with near impunity. I never did it but if I had I don't think I would have regretted it. I weighed the risks while comparing the pros and cons. In the end it's only money and these are just toys. That same sealed 5.56 can lives on my 77/22 now for you guys who get all up tight about how things should be. I have resigned it to live on a bolt action .22. My money. Who cares?

My opinion is that if it is just to avoid an SBR stamp.......don't do it. But if you have a cheap silencer like a Ranger II or whatever and need a Title I length gun...go for it. It's your money. Just know the limitations and risks inherent in the setup.
