The question is .... what is the advantage of the carbine? They chop 4.5 inches off the barrel and call it a carbine. I never really saw a shorter barrel as critical. I have carbine rifles, but if I had bought it with the longer barrel that would have been fine too. It was just a great deal at the time of purchase. I did not buy the carbine because it was a carbine. I have a Wolverine II with a 22" barrel if you like a real carbine rifle. I am sure it would be a good shooter.

If it were me, I would just get the standard Omega unless I had a specific need where this shorter barrel would be necessary. I think the Standard model would have better resale value as well. Many people do not like carbine rifles......
