Beretta, AL391 Urika All Hunting Rifles >>> Hunting Rifles by Beretta More details and ordering info. The innovative design of the AL391 Urika gas-compensating valve has taken the operating limits of the gas-operated shotgun to new levels. This 'all load' capability allows for flawless functioning with all types of ammunition, from the weakest 7/8 oz. (24 g) load to the heaviest 2 oz. (57g). With a minimum barrel length of 28' (71 cm) even subsonic load functioning is assured. The unique system vents excess gases to eliminate stress on the operating system and component parts when using heavy loads, extending the life of the shotgun. The new valve and spring assembly remains attached to the barrel, ensuring easy assembly and disassembly and reducing maintenance. The reduced dimensions of the entire mechanism contribute to the slim, elegant fore-end shape.
