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.
