Somebody removed theirs by making a brass drift and pressing the barrel out from the muzzle end but as soon as it starts to rotate with the twist of the rifling, the block at the breech end will shear off. You can get the barrel out that way and it won't(?) affect the 7.62mm bore but youir .22" liner is what we REME Armourer types call 'shagged' thereafter.
