The Otterson Lake Farm team has truly flourished over the past 10 years and we look forward to an even brighter future. The Shockwave is available in both 12-gauge and 20-gauge and retails for $455. The Shockwave reaches its overall length via the somewhat long Raptor pistol grip and the combination of a 14-inch barrel.
