Working with my 116, I notice that the lugs on the bolt head itself do not align exactly with those on the lug collar(?) immediately behind it. There is a slight rotational misalignment between them as the bolt is worked. As the bolt comes all the way back, this causes the lug collar to strike the rear of the receiver, where it causes a bump in the bolt stroke as it is forced into alignment to be able to enter the receiver, or in the worst case the bolt stroke has hung up there and caused a short stroke.

Is this a timing and truing issue? And not to be rude, but if so, how do I get hold of Fred? I've sent two emails over the past couple of weeks asking to get on the waiting list, but no response to either.

And, just to be really dumb about this - what does that lug collar thing DO, anyway? It doesn't engage with anything, just rides back and forth on the rails and hangs up occasionally as described. What is its purpose?
