Just bought one of those Tac 14 Remington 870 with the 14 inch barrel. No NFA paperwork or tax stamp. Pretty cool gun to tinker with. The model I bought comes with a one shot extension from the factory and a stabilizing brace, so has 5+1 instead of the 4+1 of the regular Tac 14. Its the Remington version of the Mossberg shockwave. Shows you how stupid gun laws are in the US.
