Does anyone know if pinning a long flash hider ( which meets the 16" requirement) to a short rifle barrel would met the legal requirements or does it have to be soldered in place. Getting a 10.5" upper in 300 blackout and plan to put together a pistol version but in the mean time would like to use it on a rifle platform.
Other question: If using it on a rifle and planning to get a can do the rifle and the can both require separate stamps? ( I'm new to this game so plead total ignorance.)
There are three approved ways of Permanently attaching a muzzle device on to a barrel to meet the BATFE 16" min. length so you don't need a tax stamp for a SBR...
1) Pin & Weld - a hole is drilled though the muzzle device and into the barrel threads. A high strength steel pin placed in to that hole, and welded in place to prevent the muzzle device from being easily removed.
2) High Temp Silver Solder (1100 deg. F) can be used to solder the muzzle device on to the barrel's threads.
3) Full-fusion gas or electric steel-seam welding.
As to the SBR & Suppressor - SBR = 1 $200.00 stamp, Suppressor = 1 $200.00 stamp - put them together, and you need 2, $200.00 stamps.
Hope this helps,
thanks Bob that's what I need to know.
