As mentioned already, it would probably be fine but in all honesty, why bother? On a gun that’s designed to handle +P ammo like the Uzi, Sten or Sterling, fine. But on S&W 76, which runs good on any decent commercial load, why subject the gun to the extra abuse? Especially when the S&W 76 lacks a buffer and the extra recoil force will likely run the bolt against the end cap.
That’s not necessarily true. If a MG hasn’t transferred in many years, ATF typically reviews the gun’s original registration to ensure everything is still correct and nothing’s missing. Many times, they’ll also request pictures of the gun showing barrel length, overall length and serial number. This can add a substantial amount of time to the transfer whereas with a new suppressor or sbr, there is nothing to review except the original form 2 registration.
Sounds to me like they made just made a mistake and taxed the entire transaction. I doubt it’s their business plan to screw people out of $14 in sales tax on every form 4 transfer. Just have him point it out to them and I’m sure they’ll refund him.
