| Known for | Designing gas pistol system for the AR-15 rifle |
Walt Langendorfer from Rhino International Inc, was an American inventor. He designed a gas piston system in an effort to convert the AR-15 (M16) rifle to a more reliable operating system than the standard direct impingement system.
More recently, the US Asymmetric Warfare Group purchased the Gas-OperatedHK 416, a M4/M16 type rifle made by Heckler & Koch using the short stroke gas piston system after intensive tests demonstrating the superiority of this system in adverse conditions (dust, sand, intensive use without maintenance) Many new gas piston systems are being proposed by US companies. All of them can be traced back to the Armalite AR18, which was already a competitor of the AR15 and used such a system in the 50's.
