Ok I am establishing a NFA Firearms Trust tomorrow. I purchased a AR Lower here at a Texas gunshow and 4473 it is specified as Receiver. The Receiver is engraved .223/5.56 cal. I want to transfer to the trust and register it as a SBR. However I want to build and specify in the NFA form 1 that it is .300 blackout Will that be acceptable since the receiver is marked .223

There's no such designation as "a receiver."



You can build into whatever caliber you specify on the form 1, original markings do not matter.




Click the Armory button above, then scroll down to the SBR forum, lots of info there.

Not a problem.  I put a 300 BLK upper receiver group on a lower marked 5.56 yet my Form 1 specified 300 BLK.  And yes it was approved.

Umm pretty sure receiver and frame are both ATF designations that can be used on a 4473. Totally separate from the part where you specify handgun, long gun, or other.

Yup.  It's also irrelevant to the Form 1.  You don't have to designate that it's a SBR made from a pistol or a SBR made from a rifle, or a SBR made from a receiver/frame.  Just specify what you're making and what the caliber is.

It's fine. Legally a gun does have the have the correct caliber marked on it. If you look at just about every barrel ever the barrel is marked and that satisfies the requirement for the marking.   The ATF form is filled out with the caliber you intended to build.

The form asks what caliber the gun is in. What's on the receiver doesn't matter.

That's not necessarily true. TeeRex nails it below. The caliber should be engraved on a Title II firearm, which has different laws/rules than Title I firearms. The barrels are usually engraved, which satisfies the requirement. Same thing goes for lowers marked "multi". You put whatever you plan on building on the F1, but the complete firearm needs to be marked.
