What is it about SBRs that make them so desirable? Is it agility? Concealability? Reduced overall length when used with a suppressor? Or is it just something people like?
Don't misunderstand me - this isn't a "why would anyone need those evil weapons" post. I'm just curious to hear from those who would know about what advantages SBRs have that make them worth the extra $200 + administrative hassle. I don't really even understand what the rationale is for their being NFA restricted.
