I meant Caleb not Calib, but I cannot figure out how to change it.
I am getting old, my memory lapses. Every time I think I want a (centerfire) pistol caliber carbine as an understudy for my M4 carbines it is because I have momentarily forgotten about my M&P 15-22. I think the M&P 15-22 is as close as you can come to a M4 in a pistol caliber (OK 22lr is a rifle caliber too.). Why would I want a pistol caliber carbine? To train inexpensively and to safely pound steel plates at 10 to 25 yards. With a can and no ear protection, it sounds like you are hitting those steel plates with a ball peene hammer. Now that is about as much fun as you can have fully dressed with a 22lr firearm. Oh, did I say I stocked up on 22lr amo before the rush?
