Tsunami Arms Type-17 Anti-Armor Rifle

Tsunami Arms Type-17 Anti-Armor Rifle aka Tsunami Arms "Rajin" Anti-Armor Rifle is the Japanese SDF's special anti-ACPA/vehicle rifle. Supplied with bipod (+1WA Long/Ext range), computerized sights, and smartgun rig (raises WA to +3). Although this gun has a special recoil-absorption system, the gunner still suffers a formidable shock from shooting. Due to the weight and recoil, a minimum BOD of 14 is required to shoot without the bipod and brace. The SDF or NPA guys wear light ACPA when they use this gun. This personal cannon uses cased ammo.
