BATFE recognizes the AR15 platform is modular so they allow temporary use of caliber/length other than that listed on the Form 4. However, if you are making a permanent change, you need to amend the Form 4 with the updated information. This does not need a separate application or tax stamp, just a letter to the NFA Branch.
