Is this normal? Stripped lower.

Wouldn't you need an upper that is also slightly offset to properly align the reciprocating bolt carrier group? (if it was an intentional design).

its not offset, one side is just larger.

Here's some photos, As you can see if both sides were symmetrical you could run into "pinch point" issues. I think its a nifty design, But if you think all upper designs have to be created the exact same go for it.

I just checked around with some makers of billet lowers and not one offers anything but symmetrical lowers. There is no pinch issue, you use your thumb or the heel of your hand if you think using the forward assist is of any value to begin with. It doesn't add up if you look at forged lowers for comparison. The blueprint for the lower receiver shows a symmetrical receiver extension tower. If there was a pinch issue it would have been fixed about 50 plus years go, no??

It was on the EE for a week or better, had two people back out when they seen pics. I decided to give someone a deal... No worries though, I just got my CC lower and it's the same on both sides...whew LOL

Shyte I missed it and I am always looking.

This is a fix to an issue that was created by trying to fix something that wasn't broken. Basically.

Maybe. I think it was designed to be thicker than what's ordinary ,and then had to remove some matarial from the FA side.
Either way it don't matter as you can barely notice it when installed and functions fine.
