Cutting a Tightbore

[warbird]

Hey guys, instead of getting a shorter tightbore, could I just cut it or would it affect its accuracy?

Thanks

You can cut it. Just carefully remove the burrs with a needle file.

[Styrak]

Yes you can cut it. But after you cut it, put a bevel in it and file/sand it smooth.

I use the "poor man's lathe", after cutting and filing, put the barrel into an electric drill and clean the end while it's spinning. I tend to use a deburring tool, but careful use of a needle file works well too.

Burrs?

I'm assuming you don't mean the planty things that stick to your clothes?

Couple years back I had a worker at a site I was working take my tightbore into the shop and chop it to fit the 416. When it came back it was smooth and there was no bits/shavings of metal (burrs?)

Just make sure you cut the right end.

haha yeh! Thanks guys!

I will need to cut about 54mm off of a 554mm 6.01mm tightbore for it to fit my VSR-10.

To be honest, I am very hesitant to do this... as I don't want to ruin a $175 barrel.

Since it's for a sniper, and it's such a tight bore, is it genuinely safe?
What precautions should I be taking?

Thanks,
Eldin

in short, NO
no matter how good you cut you will induce damage and affect the accuracy of the barrel. If you absolutely have to cutting it, and have it gradually expand inner diameter like a inversed cone shape. But personally I wouldnt do it.

Just go to a local Machine Shop and ask if they can cut it on a turning center. The job will be done smoothly and without risk. The only thing is that they will have to be carefull and not tighten the "chuck" too much. I can easily do such thing at my shop...

Buy an adapter, and a suppressor to hide the barrel?

At 175$, don't mess with it. What brand may i ask?

[Rugger_can]

Its a tube. For all the fanciness we associate to it. It is essentially a tube.


Using a very high velocity cutting wheel from a very stable platform will cut it just fine, but as Pugs said make sure to clean any burrs off afterward. If your uncomfortable doing it on your barrel then go out and buy some very thin copper tubing (usually from a custom bike/car/marine shop) and practice on it.



Cheers.

I do have an adapter that almost fits, with a bit of pipe tape, it would fit nicely, but not to hold a silencer, as it wiggles to much, but a flash hider will do.
The barrel is PDI.

I was going to replace the hopup with one that will support AEG barrels, and buy a Prometheus 509mm 6.01mm tightbore, one that actually fits.
but
Would it be better to get the longer (higher quality?) barrel, and not cut it, just use a flashhider to protect the end?
