Heard today the most reasonable explanation of the recent K-80 blow up. Look @ the photo, there appears a lot of burns on the upper barrel. This indicates excessive head space. Excessive head space will cause the barrel to cant to the right in the receiver and this will cause receiver failure. If your barrel has any side to side play get it serviced.

635 G, I might have to agree with you, but I take exception in this case. I know the old saying that the chain is only as strong as it's weakest link, BUT I have met most of the gunsmiths from Krieghoff (when they rotate thru their vendor and repair building in San Antonio during various shoots during the year, I don't "think" they have any "Worst employees". I think your comment is a little off the mark and undeserved.

Pictures were dark and taken by a cell phone......very reliable, lol.

"Look @ the photo, there appears a lot of burns on the upper barrel"........Really, no lie, for goodness sake. The thing was just blown up within 10 minutes of the picture...LOL

Why would Krieghoff even bother to send the receiver to a lab for testing when there are engineering geniuses who can solve the worlds greatest mysteries right here on ts.com....LOL

Did Krieghoff International Serivce it from Ottsville or some other Krieghoff like Allems or Dupont?

Did the barrel go in when serviced? Doubtful

So another example of you just cant hang a barrel on that some local yahoo has worked on.

The headspace may get you and servicing the receiver and forearm iron will have nothing to do with that.

I don't understand. Can someone please explain why the barrel cants to the right (never to the left?), and how this canting causes the receiver to fail?

All I know the guy who showed me a sketch, made everything super clear--its a no brainer--do maintenance on all high mileage guns--no problems

I don't own a K gun and have no intentions of owning or shooting one. The info I'm putting out is for K gun owners-HMB-- see your proctologist so he can remove your head.

Excessive headspace will not cause a K-Gun to blow up. With a lot of extra head space the gun will not even fire. This is because the firing pin will not reach primer. HMB

Guys; give Phil a break,he is a Submariner.

After the USS Thresher Admiral RIckover trained those guys to examine the issue(he never used the word problem)and recognize that even the best engineers and mechanics are capable of errors,either in engineering, procedure,or workmanship.

The data seems to indicate,at least to the casual observer, that K80s are experiencing some kind of failure rate that MAY be differnt from other shotguns.

Good engineering would tell us to follow the data, do the engineering analysis and dont be defensive.
