I haven't owned a lot of Citoris, but I did use several when I shot Sporting (still own my last one). I bought the first ones over a few years, but they were all well before 1995. I didn't pay a lot of attention to the hunting guns, but the target guns were all made with choke tubes. My very first I bought was my favorite, had the standard size tubes, and even it had tubes. I thought they had switched to tubes well before that.
