I recently picked up this Turkish mauser, it shoots about a 12 to the right at a 100 yds. So when i whacked the frt sight the whole unit came loose and fell off! looks like the pin what fits in the barrel is now up in the base and i can't get the blade off, kind of a cheap set up? Any suggestions? i suppose i could epozy it and use SWAG for windage. Would anyone know of a source for the base, pin and blade. TIA....Semper Fi
