The arms were recovered during a joint operation conducted by Assam Rifles in collaboration with the Mizoram police from Wednesday.
The team launched the operation based on confirmed intelligent inputs about arms being kept hidden in Aizwal.
The team also apprehended three individuals in this connection, who were later handed over to the Aizwal Police Station.
