To enrich the whole shooting experience, Ares have introduced 3 types of Outer Barrel for their newly released Amoeba AS-01 'Striker' sniper rifles. This particular version is the Spiral Fluted Outer Barrel which adds a very stylish element to the Striker series. This outer barrel is longer and it doesn't reveal the tip of the inner barrel. At the end of the barrel is a 23mm CW thread for their mock suppressor. You can also purchase their 14mm CCW thread adapter if you prefer alternative aftermarket parts.
