Hey everyone. New pcp shooter here. I bought the umarex hammer in .51 and Benjamin armada in .22 . The armada is dead silent and hits accurate shots at long ranges. The hammer is so fun but too loud for my backyard with neighbors around. I have two questions. Is is legal in MA to shoot pcp rifles with neighbors close by?(obviously not in the direction of them or there home) like a firearm or bow requires you to be so many feet from a dwelling but I can’t find anything online about BB gun / pcp rifle laws. Also I have some buyers regret on the armada and return date just passed. Would anyone in ma be open to a trade or can I sell it on here? I put Mabey 10-15 mags of pellets through it basically new still.
