    Problem with bolthead binding on guide rail

    I've noticed that one of my Enfields has a little problem with the bolthead wanting to hang-up on the guide rail. This is a 4/1* with the bolt head turnout slot.

    The issue occurs as the bolt head passes over the turnout. Upon making contact with the rail again, the rear of the bolt head groove hangs up on the edge of the guide rail because the extractor spring is pushing it all the way over to the right (ejection side) and it misses the guide rail slot slightly. This does not occur if a round is not present (no extractor tension) and with rapid bolt action, there is usually enough inertia to force it back into the groove.

    There has been a recent bolthead change to adjust headspace. I'm thinking maybe a weaker ejector spring may be one possible solution, but what is the common fix for this.

    Boltheads for MkI* rifles should be beveled at each end of the lug or rib that rides in the retaining slot, so that in the event the head rises slightly on passing the slot, it does not hit the corner and damage it. This seems to be a modification that was adopted later than the MkI* feature, and some users don't seem to have known/noticed, so one finds what are essentially MkI or UKicon production bolt heads fitted to MkI* rifles sometimes, with predictable results. You can bevel the slot yourself if you're handy with a suitable wedge-section or "knife edge" needle file. I think I posted a photo of the bevel in a previous thread.
