BD556 is back ! With the same ambi mechanismas HAO RBR ! Bring you more flexibility in tactical loading in 2020! 


CNC machined from an Alloy 7075-T6 billet which is as same material as real firearm.

This time we have developed a new ambidextrous structure for the PTW AR system, unlike the our 416A5 style structure . The ambidextrous on the BD556 ambi and RBR is more exquisite, it shows the craftsmanship of HAO's R&D dept.
