A friend of mine has an M4. Without me asking how well it functions, he remarked that it experiences a lot of FTEs. Just goes to show that issues are not limited to the Turkish clones. Sometimes it's just luck of the draw.
Not exactly a clone, but a Turkish made shotgun nonetheless, the Stoegers for me, have been excellent functioning shotguns. I liked the M3K so much, that I bought a M3500. I've never regretted either purchase. Sure, a Super Black Eagle owner does not need to change the ejector and spring, but by the same token, my Stoegers were not in excess of 2000 dollars. To add to it, sadly, the SBE,s are on the ban list. Not to say that the Stoegers, as well as any semi will be spared.
