Removal of rear sight from a Blaser R93

[EMcC]

Can anybody point me in the right direction of how to remove the rear sight of a Blaser barrel.
As mentioned elsewhere I have the opportunity to buy a barrel that has had the front sight removed and threaded but to get a 'thread protector front sight' is proving more difficult than I thought.
So now I am considering having the rear sight removed with a view to getting grub screws to fill the holes.
If the grub screws are going to make the barrel look like a second hand piece of junk then I will have to give this opportunity of a reasonably priced barrel a miss.
Of course, if anybody knows of a reasonably priced R93 barrel in .308 that has not been shot out or has serious throat erosion, I'd appreciate a heads up.

Angle grinder ??

I had my front siight removed from a Styre by Mark Crudgington a few years back and it looked as if he had used one to do the job, so no thanks not again !!!!

They are a major bitch to remove with out breaking them. There is a little pin that retains the rear sight. I have had fair luck with clamping the barrel upside down in a vise, in leather or plastic pads of course, let the rear sight just float in the dovetail, rap smartly with a leather or plastic mallet directly on the side of the barrel where the sight is, with luck you will dislodge the retaining pin, and it will fall out the hole in the sight. Of course if the sight base is broken, it is not a big deal, dremel it until you can get the whole thing removed leaving only the threaded pin in the barrel. Then if you can figure out the thread pitch, replace it with a Reknagal all metal rear sight.

Hi Bob,
I can't make head nor tail of any of that !
If I clamp the barrel upside down in a vice I cannot see the sight !
If I clamp it up the correct way there is no sign of pins or a dovetail !
If I did Dremel it off, I'm not sure what I would find underneath the sight and I want to have a nice smooth underside as I have no intention of fitting another sight.
I am hoping a gunsmith is going to offer some advice as I have no intention of ruining a £800 barrel

There's a bit on the Blaserbuds forum about it.

Thanks for the heads up, I'll give it a check- over.

Just tried to access Blaserbuds web site and it is down or at least my IE cannot find it, yet I had it on my favourites list.
So it seems it is still 'wait out'

Just managed to get on Blaserbuds web site and can now understand what Bob was saying above as it's almost identical to as posted there.
I must admit I didn't see any pins when I saw the barrel yesterday but I'll go back tomorrow and have a closer look as there is a picture of one on the Blaser buds site showing the pin.

Thanks Bob and Teckel,
I finally got there in the end. I only hope the screw hole doesn't show up too much when I finally get the sight off.

Mine does not have a threaded hole in the barrel, it had a welded on stud, all you can do is grind it off
and re-finish the barrel.
Mine had been removed before I bought it, who ever ground it off made a decent job of it, but although
I cold blued the shiny bit of stud it can still be seen.

Now that is what I don't want, thanks.
I have still to go to the shop so will bear that in mind when I do.
The shop was/is reluctant to take it off until I commit to buying so it could be a bit of a problem but I can still try, I'll have to wear my 'Persuasion Hat' and try again.

Sorry but I think your going to be stuck with grinding a stud off.
I have now had this on a Blaser, a single shot Baikal and a Steyr with the barley twist barrel.
I think it is just easier for them to spot weld a stud on rather than drill and tap.
The Steyr was made worse as you use a stainless steel stud, no matter how you cut and grind, you
will always have a shiny bright steel spot. At least the Blaser one takes cold blue, or you could just
have the barrel re-finished ?

Don't remind me about my Styre !!! I know only too well about the stainless stud that is the last thing I want on the Blaser.
From what you have said it sounds promising, I am searching for my 'Persuation Hat' for my next visit to the shop.

i have some screw holes in the 243 barrel and they are filled with black wax, it works well, hids the holes and saves them rusting up etc.

Thanks for the offer Bob but if it is stainless I won't be getting it but if it is normal steel, I have some cold bluing paste that will do the trick.

Do not Blaser offer barrels without the rear sight fixing?

​I ask as this would seem to be the best option but I do not know what Blaser currently offer.

They sure do, I have two in other calbres already but this is a used one on offer at a good price.
I have however, now given up on this one as I have been lucky enough to find another with the same thread as my other two barrels and with a sight that can be mounted if I need it and a magazine for just a little over what this one is being offered for.
Thanks everybody for your input and Brian, you can stop digging into the bottom of your spares box for the front sight, I appreciated the offer but as you can see I no longer need it.
Once again SD has come up trumps, thanks SD.

Glad to hear your sorted.
