You don’t need to involve an FFL, infact you might be able to SBR the HK then it’s no longer a pistol it just needs to be a 29” rifle. Check with an expert on the law! Might be the best $200 you spend.
Anyone have any recommendations for an attorney that can answer some of the OP's questions?
MSI... their attorneys are tops in this arena.
