I've had 3 of these over the years. They are an Italian copy of the an Anschutz semi-auto. I can't remember who the importer was, I think Century Arms, but not sure. All 3 rifles I had were very good shooters. I had no problems with jamming with any ammo. Each one would shoot about an inch group at 50 yards. It is no target rifle, but it is a good rifle to learn the basics on. I used to have a couple extra magazines, but I believe I sold them with the guns when I traded them off. Have you tried any of the other gun parts companies, such as Hoosier gun works or Old Western Scrounger?
