The most simplest receiver but also the hardest and classic receiver. HAO presents you the CT's M4A1 receiver set for PTW.
When the high precision CNC machine centre meets A7075-T6 alloy billet is not enough anymore for our PTW user, then is time for our mighty hydraulic pressing machine with the pony stamp on it.

We just can't only provide you the highest standard product but also the masterpiece of the milsim industrial.


We now have our HAO gen II M4 receiver. It has the later era profile of M4. Enjoy!

Anodizing/surface treatment disclaimer :Anodizing is a serious chemical process that is fairly unstable. The shade of color can vary batch by batch. We do our best to make the color as correct as possible but we can NOT generate if the shade meets your imagination. Also to be noted that every monitor has its color differences. The color of the object and the color on your computer/ mobile device may be different.
