The Sierra 7 bipod was designed to give the modern sniper, who is employing larger caliber more accurate rifles, a suitable support. The concept was developed by Daniel Horner who is a very experienced, top level competitive shooter as well as a being an active duty Soldier. Daniel listened to snipers from every facet of the Army and Department of Defense to find what they needed in a bipod. He used that information to build a bipod that met those needs exactly. Everyone agreed it needed to be rugged, reliable, have a smooth pan and track feature, a smooth tilt feature, tension adjustment until lock for both, and have absolutely no 'play' from any of the features.
Like most revolutionary gear this bipod was tested in competition to prepare it for combat. Two prototypes were used by Daniel and sniper partner Tyler Payne to compete in, and win, the 2012 International Sniper Competition in Fort Benning, GA. Daniel asked for input from the world class snipers at the competition, and made a few final adjustments to ensure that you, as the end user, would get exactly what you need. What came about was the final edition of the S7 bipod.
