Registered AR and flash suppressors?

[gr86ss]

I have a registered AR-15. I recently purchased a 6.8 SPC upper for it and it came with a 14.5" barrel and flash suppressor that's threaded on, but not pinned and welded. Do I need to permanently affix it? Is the flash suppressor legal if I install this upper on my registered AW lower or is it CA illegal? If the flash suppressor is illegal, do I need to permanently affix a muzzle brake to make it a 16" barrel?

I haven't kept current with the always changing laws and want to stay compliant with them.

thanks in advance.

There has been no change in the laws since about 1931 concerning the barrel length requirements.
Mere possession of your 14.5" barrel without a permanent muzzle device that gets it over 16" causes you to currently be in "constructive" possession of an illegal short barreled rifle unless you also own an AR15 pistol.
You should get that permanent attached asap.

I'm not positive but if it's registered as an AW already I thought it needed to stay in the registered configuration....that would mean changing the upper would be a no-no.....but i could be totally wrong!!! just something to check into. If it's ok, then what Randall said is definitely true....weld that sucker on their ASAP!!!

Nope, You can change anything you want as long as you don't make an AOW, SBR or MG out of it.

You essentially registered the lower, not what sits atop it
