So in the interest of buying dumb unnecessary things for firearms what have you found? I found this article and thought it was a good base. For me it was a rapid fire adapter for a ruger 10/22. It mounted on the trigger guard and did increase the rate of fire (and malfunctions). Useless and thrown away eventually. Anyone else have anything else useless?
