HAO's Marui MWS BCG-steel ver is made from the carbon steel with Electro-deposition finishing.


It comes with the bearing and standard Alloy made bolt end.

**The upgraded guide wheel version bolt end need to be purchase sepratly, see link below**


If you need the Nozzle set. Please see link below


We also added the HAO developed BCG enhanced sticker. Which makes the problem of jamming caused by worn off BCG polymer cap disappear.


Once the cap wears off, it loses the support between the BCG and the receiver. It will cause the BCG lift up during the travel through the magazine BBs feed and jam.


The sticker helps support and also smoother the travel ! Make your MWS more durable !


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.
