Are you sure? I thought it could NEVER go back to a pistol if it was EVER a rifle. (But I never checked. Just thought it was one way only)If you're going to go the .22LR AR route then you should buy or build yourself a dedicated .22 rifle or pistol instead and you'll be happier. Why? As mentioned above the conversion units aren't as accurate, and the rifling of the standard AR barrel is too fast at 1/7, 1/8, 1/9, etc. (standard .22LR rifling is 1/16), which can lead to premature barrel leading and even gas port blockage.
A while back I decided to build a dedicated .22 AR pistol as a suppressor host, and used a CMMG 4.5" barrel/bolt/carrier setup with a Spike's Tactical Crusader lower, and it runs great and is accurate for what it is, a fun and casual plinker. And since it was born as a pistol it can be transformed from a pistol to a rifle and back to a pistol legally. The same cannot be done with a firearm that started life as a rifle...just something to consider

Yessir, I am positive...from originally a pistol to a rifle and back to a pistol is legal, but going from an original rifle to a pistol length barrel w/stock (the latter of which is part of the definition of a rifle) requires an approved Form 1 to SBR status.Are you sure?

Ok. I thought when I bought Virgin lower I was told if it ever was a rifle, it could never go back. But I wasn’t sure.Yessir, I am positive...from originally a pistol to a rifle and back to a pistol is legal, but going from an original rifle to a pistol length barrel w/stock (the latter of which is part of the definition of a rifle) requires an approved Form 1 to SBR status.
I have a Ciener kit that has provided many years of dependable service and very good accuracy.
