ID:	36808 It's fascinating you managed to get them all so close together. I picked up 36845 from the TMP yesterday. What else is there to know about them apart from their being former gas trap rifles?
    Sorry Mr. President, the people we defeated in WW2 were not "fine people," and America's war dead are not "suckers" and "losers."

      Check and look for the low guide ribs, would be rare to find now. Receiver is revision 1

        My 36xxx does not have the sloped or wide guide ribs and it doesn't look like there is a weld. However, I thought that they had the problem in serial numbers well after 36xxx. Is that not true?

          It is not really the serial numbers - it is the revision number: about 99% of all the no revision number and revision 1 receivers have the low guide ribs. The revision 2 on up were manufactured with high guide ribs except for some overlap of a few examples

          Late gas trap rifles used revision 2 receivers manufactured with high guide ribs

            Here are photos of mine. It doesn't look like there is a weld but I'm told there is.

            - Are rifles marked with revision numbers?

                Thank you. I have seen some photos online of modified receivers where the welds were very visible, so I didn't think mine had been repaired. Someone did some nice work.

                Are there revision numbers on the receiver?
