This is the Umarex Hammer 50 caliber air rifle designed for big game hunting. Yes you read that correctly. An air rifle, for big game. Now before you say I'm crazy take a look at the specs. This this has been engineered for maximum power. It can propel a 550 grain slug at 760 feet per second producing 705 foot pounds of energy. That a lot of lead that is really moving! That not fast enough? How about a 250 grain lead slug exceeding 1000 feet per second? Needless to say this is no red rider! This is a very serious piece of equipment! It still looks new and we believe that it probably hasn't been fired outside of factory testing.
