Yes, I'm aware that it's advisable to replace the buffers and spring. I was really posting to find out about the action spring retaining pin - my gun doesn't seem to have one and I can't figure out where it would go.
The supply of bolt carriers have been exhausted as this is a fairly common problem however there has been success in welding broken ones.
Luckily, our club has a good welder turned jeweller so I'm going to get him to have a go at my broken carrier after I've obtained the spare parts.
The other three parts are fairly easy to come my in the US and should be replaced for preventive maintenance. I however I don't know what kind of parts availability you'll find across the pond.
I don't think that this will be a problem, though it won't be cheap what with postage and HMRC fees.

this is because of a weak action spring/bolt return spring ,its allowing the slide link to enter the tube to far and is bottoming out against the slide.
this is what causes them to crack
Ah, *this* is what I was after - I *thought* that that area looked a bit beat-up.
Question is, where does the spring retaining pin go? Does it fit in the area that's been, um, "re-worked"?
I'd very much appreciate a photo of this area that *hasn't* been knackered to compare it with mine.
Thanks for your replies, chaps.
