you know what you want but i just wanted to give you an observation i was just shown.
on u tube, MAINEPREPPER, talks about prepping and defense and such. he is millitary and has some good common sense and experience.
in talking about a firefight he says you need a battle rifle. a carbine that shoots a pistol rd is still just a pistol, with a longer bbl. up against an AR it might not make the cut.
i dont know, you could just want the carbine in pistol rd. i want an M1 carbine 30 cal. that wouldnt be a match for an AR either. lucky i have an AR thats full auto.
hope im not overstepping.
