Shooting range noise in Islip has neighbors up in arms – A decades-old Islip Town firing range utilized by hundreds of shooters each year — including several government agency employees — has itself come under fire from residents sick of continued gunshot sounds ricocheting throughout their normally quiet neighborhood. Law enforcement officials from U.S. Immigration and Customs Enforcement, the U.S. Marshals Service and the Bureau of Alcohol, Tobacco, Firearms and Explosives, along with state and county court officers, use the range on Freeman Avenue in Islip hamlet during business hours on weekdays. But weekends during the summer at Islip Rifle, Pistol and Archery Range are troublesome, some residents say. That’s when the public can use the 28 firing stations, and as many as 70 people are shooting “nonstop” between 10 a.m. and 4 p.m., residents and town officials said.
