Quoted:
XM177E1 (Model 609) and the XM177 (Model 610) had the flat slip ring and the XM177E2 (Model 629) has the Delta ring. Some of the XM177s may have used a Delta ring. Quoted:

So, are you saying that the 629 uses a modern style Delta ring? I'm working on a few different projects and I was thinking I needed a grey slip ring for all. (603, 604, 629) |

View Military Carbines. Note: XM177 pictures shows correct flat slip ring, but says Delta / Tapered. |

Ok, here's a follow up question...
Would one be more likely to find a straight delta ring on a XM177E2 or a Colt 733 Commando? I ask, because my 733 upper currently sitting on my M16 has a straight delta ring but is of a later vintage than my XM177E2 upper. I'm about to pull the 177 upper apart and I'm wondering if I should switch delta rings? |

I'm about to pull the 177 upper apart and I'm wondering if I should switch delta rings? Both the XM177E2 and Model 733 Commando originally sported the Delta style slip ring. So why not just add a new correct Delta ring while you have them disassembled? If I had an extra one I'd pass it along. Scroll down and see Colt Brochure shown for Model 723 and 733 Commando. http://www.ar15.com/forums/t_3_123/677983_Colt_Model_723_Carbine_build_help.html |

If I had a grey one, I'd probably do that.

| The export model of the E2 (630?) also used a flat slip ring. Lots of E1s got longer barrels or new uppers once the originals were shot out, so you have that factor too. Interestingly enough, the 651 and 652 had flat slip rings, and were mostly an export item, but came out after the Xm177E2. What this means I'm sure not even Colt knows for sure. |

I figured others would respond and help with your answer, but since this had turned into a full-on discussion I'll add my two cents, or whatever it is actually worth.
All the in-country / in the field pictures of US troops with the E1/609 show a flat slip ring. Pictures of an XM177E2 seem to be mixed, but I can't tell if these are originals or exports. I'd use a flat slip ring for either build. My logic is that the US production, based on what I've read, ended around 1970. At that time, the M16A1 was using a flat slip ring so I'd assume the carbines would be too. Later rifles could be exports or rebuilds etc, but for a US-issued rifle, I feel it would be a safe bet to go flat. Please correct me if I am wrong about when the tapered delta first started appearing, but I still think flat is the way to go. I hope this help!s |
