Ken, thats what I thought. Its hard to see in the pic of my gun but there is a fixed lug that mates with the barrel extension(dolls head) but my gun does not have the top bolt that retracts (or swivels) with the top lever. My terminology is wrong when I was talking about lugs before. I should have said the top bolt that engages the slot in the barrel extension. When I first saw your gun I was thinking that both the top bolt and tapered lug (for the second slot in the barrel extension(rib))moved with the top lever. After looking at my guns it was clear that only the top bolt moved with the lever(and of course the bottom bolt that engages both barrel lugs) As you can see with this pic, my gun has a similar slot in the barrel extension(rib) that mates with a fixed lug in the receiver but no slot for a top bolt. For lockup my guns only use a bottom bolt that engages the bottom barrel lugs.


I didnt word my question very well, I hope this clears it up a little.
