i love this thread . i have been weighing out the pros and cons for a few months over building a mp5k or some kind of dang tiny sbr carbine .
i usually come back to thinking i should just do a super short .22lr with a suppressor because i know i would shoot it everyday . but at the end of the day im still gonna be googling HK'S and Mac and obsessing over one .
truth is for me (civilian ) i have absolutely no use for one in . i want to say id slide an mp5 under my couch but i would never ever want that thing brought in court , nor would i want it confiscated in the event of home defense .
i would however consider it to be folded up in a bug out bag or some EOW situation.
in the past i would want my AR or mini 14 but those lil subguns are just soo easy to shoot, conceal and light and easy to pack ammo i think a reliable sbr carbine would be my personal choice . then again , a short barrled mini draco would be a sick packer too ....
but the only scenario i can imagine to validate a pistol caliber short carbine ( for me /non-professional) would be an, on-foot god awful end of world situation
( which then again would bring me back to a .22lr for hunting small meals .....

lol
truth is subguns & sbr carbines are just awesome

if you have the means and place to blast one you probably already have more than one , and hopefully will never ever use it for real
they definitely have their place for sure . and if you already have your 3 basic food groups pistol-rifle-shotgun, then you need dessert
