I think you need to drill it out and start over. What most likely happened was as you were setting the rivet the receiver rolled on its side twisting and causing your problem.

My suggestion is to shim your receiver o the jig for the next set of rivets. Get as much support under the receiver as you can. This will prevent the receiver from rolling over and twisting

Akbuilder rivet jig works like a charm.
You prolly didn't tighten the screw thing down tight enuff to the horse shoe thing that sits on the reciever.
Did you shim under the reciever w the rubber blocks that comes w the jig?

I agree with kc drill it out start over I use a c clamp to holding the trunnion and receiver tight together and lined up. I don't use the jig for the trunnions though

Try cycling the carrier and see if it binds or doesn't ride smooth. If you cannot get a picture of it, it will shoot.

If it bothers you, start over.

start over. its a gun. your face will be right there if something goes wrong.

Just make sure all your holes line up. Dermal them out if they don't. A little misalignment becomes a big problem if the rivets try to straighten every thing out. The trunnion is a more rigid piece and if the receiver holes don't line up with the trunnion three diver will flex, twist, bend to line up right. Happened to me on a tapco flat. Had to cut it up and start over.

The support the receiver and give it a go.

Those blocks and those buck "buttons" suck balls IMO. What you need to do is make your own buck bars, I made mine out of 1.250" round stock. I used a 7mm ball end mill to make the cup and turned the profile so the receiver sits just above the flat of the bar. Also, get some HDPE from Tap plastic and make a plate that supports the entire length of the receiver. I'm around a 98% perfect rear rivet rate, but I can also fix it as long as I catch it first.

Also, make sure to tighten that guide down really good, and that you can spin the alignment ram freely. If there's any resistance, it's not straight. Take the time and do it right the first time, if not....well you'll take the time to do it the second or third time correctly.
