This is the Magpul Bipod for Sling Stud QD (Quick Detatch) mountings.
With a frame of lightweight Mil-Spec 6061 T-6 aluminium encased in Magpul's extremely durable polymer, the innovative low profile design conceals all the internal mechanisms in a snag free layout.
Optimised for rapid single handed adjustments the bipod quickly and quietly transitions between different firing positions.
