Hi all
I have a BSA Meteor mk3 made in 1972
It has a upwards bent barrel from a sudden barrel release
I really want to fix this as I love the old BSAs that is until gamo turned them into sh*t.

Any advise on how to fix the bend is much appreciated
Photos to follow

Hello and welcome to the forum.
Have you tried aiming a little lower? :)

But seriously there is not a lot you can do to get it back. How bent is it and is there only one bend? also what engineering tools do you have access to?

I can tell you the best way to go about it but you will need some specialist tools like an Arbor press and a magnetic dial indicator and some V blocks or something like that

Hi thanks
For some reason I cant upload photos
There is only one bend but it is visible even though it only is a few degrees

When you say you cant upload photos what do you mean? do you get an error?

Hi,
just yesterday I was talking to Myson from the forum who mentioned he knew someone who had successfully straightened a bent air gun barrel after a gunsmith telling him it would  be very expensive to try and be unlikely to be a success.   Be worth reaching out to him for more info.

Other than that, it would be worth contacting Ron at Youngs Airgun Center (www.youngsairgun.co.nz) - he may have a spare barrel somewhere.  I see he does have a  Meteor MK1 that is missing a rear sight for $90 listed on the "Collectables" page of his website.

You may be able to get a replacement barrel from either TW Chambers (https://twchambers.co.uk) or Airgun spares UK
(https://www.airgunspares.com) 

Good luck - and welcome to the forum.

A quick fix for reducing image resolution is to create a collage, or crop the photo slightly. If you do that, then check the photo details to see if the resolution size drops below 406.

Or set camera on lower esolution when taking the photo.

Hi Airgun1,

Yeah, as EC says, I have a mate who's lovely old Weihrauch HW97 .177 was thrown out of a car during a robbery (!) and the barrel bent.  Angry

No gunsmith would touch it because the risk of failure was too high.

So he decided to have a go and fix it himself.  He built a wooden frame that allowed the bent barrel to be hammered in the correct direction.  He then used a heavy rubber hammer each day, bit by bit, and he hammered the barrel straight over 3 months!  And he did it all by eye, no intricate measurements!

I've shot that rifle since and it shoots beautifully!  You'd never know it's history!  So there's hope for you yet!!!

But I'm sure Ron Young would give you far better advice than me!!!!

Good luck!  Smile

I had a Gamo and Diana that both ended up with bent barrels. Ron attempted straightening the Diana and it was only slightly less rubbish after his attempt i.e. it was a waste of money. I think your best bet is to purchase a new barrel. There are videos on youtube of gunsmiths straightening barrels so maybe there are more competent gunsmiths out there!

One thing to remember also is the airgun barrels are not the same as a power burner barrel. they are made from a softer steel because they do not have the same internal pressures involved as a rim fire or center fire rifle has so you will have a better chance of fixing it.

Finally
As you can see when thw action is resting on it scope mounts the end of the barrel is keeping the rest nearly perfect horizontal
I think i will try the jigsaw method as I bothered Ron enough with new parts did I mention prior to the bend I installed new spring and seal kit

It's certainly worth a try and with a bit of care you might just be able to sort it.  I personally would find it hugely satisfying to fix something like this.

At the end of the day you should be able to source a replacement barrel if you don't succeed.

Good luck - and keep us updated on your progress.

Does it still shoot? And if it does, is it still grouping consistently?
Usually springers suffer from barrel droop and scopes need to be shimmed.
I’d say rather up then down… 😂

Id insert the muzzle end into the space between the top and bottom of a wooden pallet, apply some pressure on and off till its good.
i had a similar problem years ago on a Diana 31 Panther( synthetic stock) 

That waa the advise given to me from old times on the old Dianawerk collective forum.

Took a few goes at it but I got it sorted

Dont you know someone with a hydraulic press - or better a manual arbor press?

Its just a steel tube , no differant to a piece of pipe , so can be gently pressed back into some semblence of straightness.

Im seeing large amounts of overthinking at work here ......

To me it doesn't look look like the barrel itself is bent, rather poor matching of the breech mating faces allowing the barrel to rise above the cylinder centreline.

Not easy to fix, and having rebuilt a Meteor roughly 12months ago, they're junk and not worth wasting time on (IMHO).  The engineering is appallingly bad.

Can you put strait edge against the barrel from the the spring cylinder just past where the barrel closes against it and along the barrel so we can see exactly where the bend is happening?
Use a contrasting back ground like white under it and focus the pic till only where the barrel is strait. The strait part ( apart from the first couple of cm is of no relevent need to the picture. Maybe rest the ph on a couple blocks of wood so its a steady and a sharp photo.

Im thinking its the whole breech block and barrel thats pointing upwards... I dont think the barrel is bent.. 

I would probably try shimming the scope rings. if you have open sights they are usually on the breech block so doesnt matter if its not straight as front and rear are both on the same angled line... 
I had a BSA lightning that had an upwards barrel - shimmed front mount with some milk bottle strips and I could get it zeroed ok at 25 yards

Im guessing that someone who joined 2 days before, said he loved old bsa until gamo took them over, then got told they were junk and not worth working on decided to skip the site.
He wasn't looking for opinion he was looking for help.
Wouldn't blame him. People don't want guns they enjoy rubbished.

Don't overthink the barrel straightening. It doesn't need to be surgically straight from end to end.
It only needs to have the muzzle approximately where the sights / scope rail align usefully.
Take advantage of a small bend near the breech producing a large deflection at the muzzle.
It almost certainly bent at the breech end to begin with, due to the physics.
So you will likely be reversing the bend where it occurred if you only clamp the breech end
and pull it back down.

I'm also interested to see how this worked out.   In my early teens, around the time this gun was manufactured, a good friend had a meteor and it was the first air gun I regularly used.  I have fond memories of scaring the local sparrow population with it. I recently purchased an early super meteor of a similar age from Ron Young.    Mine is a bit rough looking but having been serviced by Ron does shoot smoothly.  I ran it over my crony this afternoon and it is putting out 8.5 fpe at the muzzle  with 36 fps between the highest to lowest speed over 10 shots.

I'm looking forward to some fine weather so I can see if I can shoot my one any better than the one my friend had!

My very first air rifle was a super meteor. About 40+ odd years ago. Knew nothing about air rifles. From new shot a shyt load of mums pegs off the clothes line one arvo. Shot a white butterfly on the wing. Filled the neighbours gutter up with sparrows. Won the trophy at the local air rifle club, for juniors. Blew the flame out on a lighter at approx 25m and kept me mate pinned down behind cover when we were busy hunting each other in a vacant scrubby subdivision across the road for 10min. He extracted his revenge with his co2 revolver, when i tried to change cover. Three huge welts on my leg from six shots he took at me while i was running between cover. First air rifle i ever hunted with. Absolutely loved that rifle. Totally got me into hunting. Awsome gun. Awsome memories. Awsome time of life, wouldn't get away those shananagines these days. But back then it was just being a kid. 👍

Yep - the world we grew up in has gone for ever ,

Nowadays the fun police and poor parenting have taken risk and inventiveness away from children.
