So found this gem on Trademe today....
https://www.trademe.co.nz/a/marketpl...ing/4410602477
Stripped screw in receiver, bent barrel, barrel looks to have been ground down for scope clearance, and looks like thread tape and an O-ring on the muzzle threads.
Would love to know more about what happened to this rifle.
Lol what a pos. They would have been smarter to pull the barrel and sell the action/stock.

so if its bought and some foll blows head off with warm factory load....will they be liable???? not sold as unusable....guess labeling as a parts gun covers the arse somewhat.... yip agree pull barrel and sell it as parts..... but hey its that "certain retailer" again... cant expect anything better really.
"and has a right hand slight bend in the bore due to accidental damage" :D
Plumbing tape and O ring on muzzle thread hints at another major fault
Cmon guys its only my first custom gun build.....
It's pretty easy to straighten a bent barrel.
I did a mates 308 barrel massively bent on a quad bike roll over.
Honestly I thought even if I got it straight there would have been out of round.
So first I used the hydraulic press to get it straight enough to see through the bore.
Then moved to the fly press and got it straight to my eye.
Took it to Mr Vulcan Barrels to se if his digitally calibrated eye agreed and yes it was straight.
Went back to mates and shot perfectly and saved a complete rebarrel
So if there was anyone remotely skilled at the retailer it would take less the 5 minutes to straighten a barrel like that
Pig hunter’s rifle. Guaranteed.
Ive straightend one as well. Thread wouldnt be to hard to deal with either. Just cut it off and rethread..
5/8"-24 with thread tape, whats to bet the surpresor was M16x1
Yup it's rough, but advertised honestly, I really don't see the issue.
Bought plenty of rifles advertised less honestly that weren't through that "certain seller"
Plenty of sub par rifles get passed off as sub moa :ORLY:
I'm sure good old Stevie68 will still snap it up.
Now they are saying its bulged as well as bent!
I was trying to make the end of the barrel look like a toz
They've clarified in the comments that the barrel is also bulged.Quote:

Maybe the previous owner wanted to time the suppressor accurately, OCD in overdriveQuote:

Running a nice heavy bead with a Arc welder along the left side of the barrel might sort out the bend.Few slaps with a hammer on the bulge after a bit of Oxy on the bump followed by a "rattle-can" Cerakote job and its worth twice that.
Follow me for more practical gunsmithing ideas
Cant you just adjust adjust your scope settings in the direction of the bend to compensate ?
you forgot holding it with curve facing up and anvil attached to dodgy threads on barrel :PQuote:

Must've had the odd bent one.
Also seen a video of a manufacturer straightening cam shafts. Thats was quite neat. All doable especially if you have nothing to lose
Akaroa has the right idea - a barrel is simply a metal tube after all.
Fly press it and eyeball the internals of the bore as you go. A bit at a time , gently does it . Cant make it any worse than the starting point so nothing to lose.
That is probably how the base screw was stripped!Quote:

Actually gently does it doesn't really work when straightening barrels.Quote:

And hope you went far enough to allow for the spring back.
Gently does it and you will be There all day with the barrel behaving like a spring
In my old fitter days we would straighten hydraulic cylinder spears. You always had to push them a little past the point of straight to allow the spring back.
Some would comply easily some had to be pushed quite a bit past it.
Using a dti under it for a good indication
If you saw the technique the old timers who made Lee Enfield barrels used, you'd be quite shocked. They had a chunk of tree trunk, and they eyeballed the center of the bend and whapped the outside of the bend right on center on the trunk. Effectively used the spring back against the bend so that after the thwack the tube springiness tended to hold the tube straight rather than springing back off the bend. The shocking thing was the speed at which they worked, less than a minute a barrel most times.
I would suggest the tree whack method is a gunsmithing mythQuote:

It covers in ever stage and every machine in the process of making service rifle barrels in huge volumes
Attachment 237268
Even down to the multi story buildings for the cutting oil from dozens of machines to drain and be filtered to be pumped back to the machine rooms
There are many pages on barrel straightening and the hammer and block method is preferred to the machine method due to speed of experienced operators

This is a truly fascinating little book and I should make some copies
I expect there are some 303 tragics who would love a copy
Whacking a barrel on a tree brings real meaning to being a "Shade Tree Gunsmith"
I had a scan of an article on that process, there was one older lady at that particular armoury that did the straightness inspection on every barrel. Picked it up, held it up to a window with a shade line hung on it and turned the barrel twice while looking through it. "Straight, straight, straight, fail, straight, fail" - that quick. They went from her to the dudes doing the whacking and passed back to her for the reinspection. Might have even been in Longbranch factory with the canucks if memory serves. There was also a magazine article in one of the US rags about something similar, a guy took a fall of a horse and bent his rifle's barrel, broke the stock and smashed the scope. He took it into a gunsmith and sales outfit, the gunsmith took the thing out back stripped the busted stuff off it and straightened the barrel that same way. Then fitted a replacement stock and scope and sent the guy out back to sight in... I think we get a little precious sometimes with how accurate we try to get!
It comes down to the fact that a bent barrel is going to be consistent at any given range (baring harmonics).
Good luck to them with that sale
This guy doesn't seem to think it's a myth...Quote:
