OK,
I am a NFA virgin, and am seriously thinking of losing my cherry as far as an SBR goes. I want to take an existing weapon and SBR it.
Which is easier as far as paperwork and tax stamp goes, to take an existing AR pistol and do the filing to turn it into an SBR ?
Or, take an existing AR rifle (Carbine) and do the filing to turn it into an SBR ?
