Lik2hunt:
You have it correct. I have sent and received rifles to and from out of state. All that is required to comply with Federal law is that the rifle/action must be received by a current FFL holder, who completes any needed background checks and the Form 4473 (Yellow sheet, which is now white, again.) If you are sending the rifle/action for repairs, such as to NEF or a licenced 'Smith, the rifle can be returned directly to you. I know some locals might have state, county, township, or other guidelines in addition to this, but this is what the Feds require. Thankfully, here in Montana, the Fed guidelines are all we have to comply with.
As has been already stated, when in doubt, check with your local authorities. DO NOT take just the word of some local gunshop. Of course they are going to recommend you ship the rifle/action out thru them, for a fee.
Please note I haven't even mentioned handguns. That's another story.
With all the inquiring/investigating minds we have on this forum, I'm surprised someone hasn't posted the exact Fed Directive yet.
