Changing upper for a registered AR

[jerryl899]

I remembered when I registered my post-ban AR15, I had to specify the barrel length as 20". The the registration confirmation letter I received only showed Serial#, Make, Model, Type, and Caliber. There was no mentioning of barrel length. Does that mean I can swap my 20" upper with a 16" upper without any issue?

Thanks.

In one word yes. The lower is the registered part (firearm)

[MrPlink]

Change away!

Yes, you can change the upper.

You can also change the stock (fixed, folding, or collapsible) and pistol grip.

The only thing you can not do is put a barrel less than 16 inches on it. And the rifles overall length must be at least 26 inches.

Other than that... go wild!

You can have shorter barrel as long as there's a perm muzzle device and 26 inches is for rimfire centerfire is 30 inche I believe

+1

Also, 26" pertains to non-semi centerfires as well.

Thank you for the clarification I did not know that part it's good I learn something new

in this case, it is 26" for both rimfire and centerfire.

Why would it be it's a semi auto

[Ed_Hazard]

Why would it be it's a semi auto

Because it is a RAW, and the legal minimum is 26" on RAW.

[ke6guj]

Why would it be it's a semi auto

because in this case, the OP has a Registered AW so there is no 30" rule in play here.

Becauase the ban does not apply to registered AWs

[kris smith]

He said post ban not pre ban

[ke6guj]

He said post ban not pre ban

post-ban as in post-federal AW ban, 1994-2004. He stated that it was "registered" as a CA AW, most likely during the 2000 registration period, so even though it was not a federal AW (hence "post ban"), it was a CA AW. Once the federal AW ban expired, he was free to modify his rifle without violating any federal AW ban. And since it is already registered as a CA AW, the CA 30" rule does not apply. And neither does the CA feature ban apply
