Made in the U.S.A, the AD-BP-P2-TL Bipod Mount enables you to attach a Harris-S, Swivel bipod to your railed forearm. Not compatible with the Tac Lever (Lever interferes with the bi-pod itself). It is precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize. It features the Patented QD Auto Lock Titanium Lever system to accommodate both in spec and out of spec rail systems. The mount includes two different sized delrin sleeves to accommodate both Harris and other brand bi-pods that swivel.
