At the heart of every A400 is the Blink operating system which delivers reliable, superfast feeds across a huge range of ammunition. All models feature Optima-Bore with the Optima HP choke system and are manufactured using Steelium, a unique grade of steel exclusive to Beretta, which ensures exceptional strength to weight ratio. Versatile and light, with a unique brown/bronze receiver this model is a stunning and innovative addition to the A400 range. The Action is also the first Beretta semi-auto to be available with a left-hand receiver.
