Having 23nd 300 blackout upper

General silencer discussion. If you want to talk about a specific silenced rifle or pistol, it is best to do that in the rifle or pistol section for that brand.

All NFA laws apply.

Having 23nd 300 blackout upper

Post by copk9 » Mon Sep 14, 2015 7:32 pm

its my understanding that if I wish to put another NFA upper (300 Blackout) on my already
registered lower SBR in 223 that I don't have to do anything as far as registering anything unless I get rid of the original upper .Is this still true ?

Thanks for reply's

Long as you can put it back to what's registered its still legal according to ATF FAQs.

And if you want to change it permanently, you just write them a letter about the change.
