2021 DEC update: We have converted all HAO PTW receivers to adopt the new PTW Infinity gear box and motor. It's now Value kit (Kumi motor) and Infinity kit both compatible. Now the kit you order will come with the RS spec grip adaptor. 



RBR is HAO's latest innovation in 2019.


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 RBR is more exquisite, it shows the craftsmanship of HAO's R&D dept.


(The fire selectors in the photos are the BD style’s. We have the new RBR style version. Please see the link following. 

You can find most of the accessories on the blaster on 2nd pic in our site. )
