I'm weird when it comes to aesthetics and how some guns are "supposed to be"
To me, a carbine is supposed to have a 14.5" barrel. If I can't have that then I see no reason to half-ass it. May as well just get a full-length 20" rifle.
So I guess there will be no carbines or commandos in my future until they either repeal the NFA or I feel like paying the SBR tax.
