Back in the day my Charter Arms AR7 (this was 1983) was the most problematic and disappointing firearm I ever owned. I had high hopes for it and (prior to it breaking for good in under 12 months) I don't think it emptied a complete magazine without a malfunction !! At the time I also had a Rossi .22 pump (Gallery Rifle) that put the AR7 to shame !!!!!!!!
