The PSR Atlas Bipod is an upgraded V8 that developed into a series of its own through military testing. The BT46-LW17 was selected for the USSOCOM Precision Sniper Rifle (PSR) Weapons System. Features non-rotating legs and estimated 40% stronger than the V8 Series. It is the hard use bipod of choice for professionals globally. Made in the USA. The BT46-NC model Atlas Bipod is part of our PSR Series. The “NC” stands for “No Clamp,” meaning it requires any 17S size mount in order to attach to a firearm.
