Buffer Technologies Inc has announced the the new ACB-4 Combat Bipod, from TangoDown LLC, designed for use with the entire AR-type family of weapons. Made of proprietary advanced injection-molded polymers and forged aircraft aluminum components, the TangoDown ACB-4 outperforms all others in design, operation and dependability. The ACB-4 Bipod also matches function to the design. It has the ability to cant and, more importantly, traverse. This allows accurate, rapid tracking of moving targets. It can also be reverse-mounted for depressed angle fire. The legs are adjustable in length, and the entire unit is silent in operation. There are no exposed springs or screws to catch foliage or webgear.
