I was surprised the first time I stripped a Yeldiz shotgun. Both the O/U and SxS internals are CNC and investment casting manufactured, and they are well done. Whilst they have aluminum actions, they are never the less well worth the price paid. These are not ironmonger's junk with stamped steel parts, such as we have seen on other guns from Turkey. The barrels also appear to be brazed at key points with the remainder held together with expoxy. New expoxies are marvelous chemicals, and I believe Teague uses this in their barrel liners. But for 5 or 6 hundred pounds they will do their work very well indeed.
Review the "Shooting Times" website for a review of the Yeldiz. From what I can determine the price in UK is a bit higher( may 30%) than what is being paid in America for them
