    a chop saw comes to mind. If it is permanently mounted whether it be blind pinned and/or welded, it's permanent and the only thing you can do is cut it off. Judging by the looks of the barrel if you cut it off the barrel will be shorter than 16." I don't know what your laws are, but in the states you can not at any point in time own a rifle barrel that is less than 16" otherwise it becomes an NFA issue...big no no. The only way to cut a barrel down to less than 16" is through a Class III gun smith and I believe a NFA stamp.

    Just something you might want to look into.

    Not really...but it depends on your expertise. Additionally, shortening the barrel that drastically might mess with the gas system and cause the rifle to function improperly or not at all.

    Probably silver soldered. A propane torch to heat the solder should soften it enough to unscrew it. I do not recall if Oly used blind pins on these.

    guys
    just a think...
    i compared the flash hider mounted with a vortex i have here...
    the area where the barrel is threaded is the area marked in blue ( i measued it the internal with a caliper)
    so,
    compared with the mouned flash hider...
    if there is a pin welded...it could be only in the red area...
    or not?

    Robocop is completely right, I forgot about Silver soldier. It's a high temp soldier.

    Sorry about that

    Just something to think about but there is no barrel under that extension and you may wind up with a sub 16" barrel, also doubt there are threads for mounting a traditional flash suppressor. Don't know if that's an issue in Italy or not but that muzzle extension is there for a reason other than looks cause it's damned ugly!!!

    well...
    if i look into the flash hider with a surfire, see the barrel , that end where the 2 rings on the flash hider ended
    and then there is in another internal ring

    Call the manufacturer or take it to a gunsmith.

    I think you are in over your head and may render the weapon worthless.

    If it's an Olympic made in the US (I realize he's in Italy) the barrel needs to be 16". If the flash hider brings the barrel to that length, it MUST BE permanently attatched and according to BATFE standards, silver solder is not considered permanent. The mark you found looks to be a plug weld, or a hole for the pin which has been driven below the surface then filled with weld.

    Drilling out the weld will probably cost you more in drill bits and frustration than a new barrel. Just a thought.

    the Oly was made in the usa in the 2006, i dont know if for the US market or for the export
    the serial number start with a E letter...
    it may mean export.. or not.. is only a supposition

    i bought it yesterday here in italy.

    about to have a new barrel... i cant.. here in italy we dotn have it on sale... and... buy it there in usa cost more in burocracy and papers than the real cost of the barrel....

    I guess if you have the time and ambition you could attempt to drill it out, but I think Cane pretty well concluded that if you contact the manufacturer they could tell you A) If there was any difference in export models and B) How the flash hider is secured.

    Your English seems perfectly fine to get the point across to a tech rep. Maybe email them if spoken English is more difficult for you?

    guys
    is possible that the pin is in the position number 2 so it pass near the barrel thread and not like the #1.. on top of the thread...

    it explains why the hole is at 2 o'clock and not at 12 o'clock...

    btw i saved the old fh and i can mount it till the new come..
    is a bit ruined..but serviciable...
