Singh assembled at least one AR-15 using gun parts that were purchased legally, the Suffolk County District Attorney’s Office said in a statement.

“This as an individual who was not legally allowed to possess firearms, and yet he was building and selling his own illegal assault rifles,” said Suffolk County DA Timothy Sini.
