CMP $100 Barreled receiver

Has anyone noticed that this receiver has an extra wide rib on the left side, less than a dozen receivers have been found with this extra wide rib

I noticed it.

Any way to post some pic's - congrats on the cool 5 digit and the barrel is possibly quite intriguing ...

Follow up to the 7th round issue. After a good cleaning of the ribs they show to have been fixed but the top of the ribs have been banged up or peined for some reason. Wishful thinking on my part but atleast I have a prewar receiver. Have to wait til I get it together and see if the fix still works or not. But for $100 I'll still keep it.

I have this 7th round photo before and after, a bit fuzzy but it shows what we need..........Photo was copied from the forum, poster name not saved.

So the 7th round modification was done on only the clip latch side of the receiver correct? Was there any modifications to the Op Rod Side?

Look closely at the picture,compare the rib to one of your rifles. Open your eyes WIDE,the difference is staring right at you.:thup:
