Constructed of hard-anodized, aircraft-grade billet aluminum and weighing in at roughly 20 ozs., the U.S.-made Accu-Tac SR-5 QD is a heavy-duty bipod that will shrug off a lot of hard use. A quick-detach mount allows the SR-5 QD to be secured to any three-slot section of Picatinny rail in only seconds. The spring-loaded legs can be independently deployed in any of five orientations and five heights, and can be retracted for rapid stowage with the press of a lever. Price: $275.
