An RG .22 revolver, true POS Almost equally as bad was a Beretta Jet Fire in .22 short. It jammed every third round at least, light strike misfires. I tried everything to get that thing to work. Only reason it doesn't beat out the RG is it was all steel, wasn't dangerous, and I sold it at a gun show for more than I gave for it.
I have an Charter Arms AR7 and like it. It shoots fine. Never met a .22 I didn't like. Well, there was this OLD rolling block Remington my uncle had, gave it to my cousin. It was just old and unsafe. I guess the AR7 is the worst I own now just do to the terrible triggers those things have, but it functions 100 percent, is accurate enough for hunting, and stashes in a motorcycle saddle bag, the whole reason I have it.
If you have problems with an AR7 feeding, you need to get the right bend in the feed ramp on the magazine. 99% of the time that's the problem. And, BTW, I also have a charter arms explorer 2 pistol that's the handgun version of the AR7. It's 100% functional and quite accurate also and also has a terrible trigger.
Never owned a really bad one. I guess the worst made, worst trigger was a Savage M340 in .30-30, but it wasn't a bad gun. Oh, an edit, worst I just remembered was an old Spanish Mauser in 7mm. It was in decent shape when I got it, good bore, had it drilled and tapped and put a scope on it. But, it was only decent hunting accurate only with 175 grain round nose bullets. To be fair to the gun, though, it was designed to shoot heavy spitzer FMJs, fast rifling twist. It did NOT like 140s at all. It was a cocks on closing bolt, too, which I didn't much care for.
