My first Sniper Rifle replica! And this one shoots 6mm Plastic Airsoft BB's using the spring powered bolt action. The ASG AW .308 Airsoft Sniper Rifle has an all metal barrel and bolt assembly with a polymer stock. It is setup to take a picatinny scope mount and also a bipod up front. You can expect to get close to 450fps using lighter Airsoft BB's but I recommend going heavy and losing some fps for better accuracy!
