The folks at AVA Tactical have developed a slick looking light and accessory mount for the Benelli M4 Shotgun. The ultra low profile mount is suitable for flashlights sized from 0.8″ to 1.035″ and does not need to be removed for field stripping. It weights 2 oz. and is manufactured from Anodized 7075-T6 Aluminium. Its only downside is the price, at $179.99 it is not cheap.
