Established 2002 Mangle Gore was the first and only spring loaded hammer in the 3lb class. Now after decades of neglect and iteration Mangle Gore returns stronger than ever as a 4s 4wd combination of tpu, titanium, spring steel, carbon fiber, ar500 and way too many plastites. The hammer mechanism utilizes a slip gear with a rack and pinion to compress and release a 50 pound spring swinging the 6 inch hammer arm over 180 degrees.
