This lightweight bipod from Smith Enterprise attaches to any MIL-STD 1913 Picatinny rail and features aluminum legs that instantly extend at the push of a button. Six precision-cut locking notches allow you to adjust elevation from 7" to 9", while the aluminum ski feet give excellent stability on any surface or terrain. Steel, TiG-welded main body stands up to hard use and helps ensure a long service life. Two adjustment nuts help you find the perfect amount of tension for the rail attachment, and the right-side throw lever enables instant mount and dismount. Legs fold forward or backward for easy carry, even when extended.
