A SBR seems ideal for a home defense gun.
I good way to go deaf.
Like most things in life, there are always trade-offs. Rifle cartridges (i.e. 5.56) does raise the risk of over penetration of walls in an indoor shooting scenario; probably not ideal in a condo or apartment setting or even a large family home with multiple bedrooms. Some folks might be better served with a pistol caliber carbine, short barrel shotgun or high capacity handgun.
Successful home defense begins long before anyone even thinks of trespassing on the property, with careful appraisal and assessment of the individual circumstances and tactical requirements one is most likely to face.
Fortunately, the American firearms industry is diverse enough that there are products for almost every niche, and repeal of the NFA would allow for even more diversity for the American citizen.
Yep.
SBR laws are stupid.
Less concealable and more accurate than handgun so that can’t be the reason they are illegal.
Not nearly as ideal as a SBS (shotgun).
