planning my first ar build but have a question

[the_snowman1]

Will the lower be registered when you purchase it from the dealer or do I need to regester it after the lower is all assembled

 

[fireball]

Lower is registered to you when you buy it. It doesn't matter about all the lower parts being on it. Once the upper is attached you have 30 days, I believe, to call it in and report it's completion and barrel length.

The rego paper will list it as "receiver only" until you change it.
