We just posted a page https://www.guntrustlawyer.com/form5.html on completing an ATF Form 5 (5320.5). Remember a Form 5 is used for a tax-free transfer to a lawful heir. If you own NFA firearms individually, you can give your lawful heir the choice of taking the item individually, in trust, or as permitted by the ATF under the NFA and creating properly drafted documents can help make this process unnecessary or easier than using the default methods found in most wills and estate planning documents that are not drafted to consider firearms.
Additionally you can avoid this entire process with a multi generational asset protection gun trust. We have Gun Trusts that can be setup to last form generation to generation without future transfers or the tax stamp fees.
