Trying to find the best bullpup? Gunprime has a great selection of the best bullpup rifles and shotguns on the market. Bullpup guns have the action behind the trigger, which makes them generally shorter in length - it almost looks like you pushed the barrel and stock together!  Bullpups combine the advantages of a longer barrel, like a higher muzzle velocity, with the shorter size and lighter weight of a smaller gun. Some great examples of bullpup rifles are the IWI Tavor series and the Steyr AUG.
