07 SOT question on making samples.
Can an 07 SOT make and register an HK trigger pack by it self or does it have be married to an actual rifle?
Same question, different platform - Can an 07 SOT make and register a DIAS or does it have to be married to a rifle.
No, it doesn't have to be married. That defeats the purpose of a post sample pack.
Just make sure you engrave ffl name, city, state, serial on each of them following the NFA requirements.
Yup, just engrave the pack and not the upper.
Most of my packs have something in the additional description field stating that it is a conversion pack.

This is purely additional to help prevent confusion during an audit. The pack is the MG.
