I kind of shake my head at the naming of these as what the classes really are is AR15 classes. I have 0 issues with that but it’s just curious. I’ve also heard the young guys on Reddit and the boards call all of their ARs “carbines” and it seems in 2021 the word “carbine” is now ubiquitous in meaning “AR15.” They’ll say “I got a new carbine” or “I saw a carbine at the store” and it is just another word for the AR now. But when I was coming up, THIS was a carbine: Here is my 1943 Underwood USGI WW2 .30 U.S. Carbine, M1. Pretty sure most of the guys with their AR15s would laugh out loud if I showed up at one of these so-called “Carbine Classes” with this old wooden warbird! Most probably wouldn’t even allow such an antiquated gun. I don’t know, I think it’s a fun little rifle and it suits a dinosaur like me pretty well. Just the ramblings of an old coot who’s had too much Turkey for one night. Take care and god bless.
