Their products include shotguns produced for Browning Arms Company and rifles licensed by Winchester Firearms.

Modern history of the company began in 1946 as harpoon cannon producer for the recovering Japanese whaling industry, expanding into firearms after the San Francisco Peace Treaty in 1951.

This model was popular with Australian rabbit hunters due to its low price and a high magazine capacity of 15 rounds.

Miroku's guns manufactured for Browning are sold in markets where Browning-branded counterparts are scant or unavailable.

Miroku also produce, under license through Olin Corporation and Browning, the Winchester's famed lever-action and falling-block action rifles.
