Re-Registering Barrel Question

[m14fan]

I recently bought an 11.5" barrel for my 10/22 off of EE, when I do to re-register the barrel length with the CFC do I need to know who manufactured the barrel?

I already tracked do the FRT# for the forum.

I simply sent a registered letter detailing the length of the new barrel and indicating the overall length of the firearm. I received my new certificate no problem and no questions.

PM me if you would like to see a copy of the letter I sent
