The Reba Interview you didn’t expect to see!

Mark jumps right in with his next interview. I’m not sure what difference it would have made if Reba couldn’t “shoot right”, by which I wonder if she meant “shoot straight”?  Apparently, Reba has trouble with chronology and transitions, since panel 3 looks like there should be one or more panels between it and panel 2. So, fine. Reba was motivated by feral hogs beating up her fields. And I see the pseudo-patriotic parody going on here: “I’m gonna blast those commie hogs to kingdom come!

What I don’t get is the rifle she is holding. What the heck is that thing!?

I’m not conversant on the many styles of firearms available, but I’m fairly certain none of them look like what Reba is holding in panel 4. That looks like something somebody might draw without having an actual rifle or photos of an actual rifle on hand. But tell me if I’m wrong, people. Please correct my ignorance. Is Rivera just being lazy or am I more ignorant that I think?
