For as long as I can remember, I've wanted an SBR and a SBS. I guess the idea of more paperwork, and not being able to travel state to state as freely has kept me from ever getting into NFA stuff. I now have my 870P and Colt LE carbine all set up how I want them, except they still seem too long (18" and 16"). I'm hoping you guys can talk me into going through with filing, or talk me out of it! The 870P would get a 14" rifle sight barrel, the Colt would get a 10.5" barrel.
