Thundercrack Rifle

This Heavy Sniper Rifle is a unique firearm which crackles with thunderous energy. Thanks to a modified breech loading wheel lock which fires thru a Tesla Module elongated barrel, the Thundercrack Rifle fires with extreme precision and incredible range.   After each shot, electricity polarizes your skin with enough electrical discharge to let you know you're alive!
