HAO L119A2 MWS kit is just perfect but sometimes it's just too heavy for the game.
Now we have the alloy version of the barrel for you.
It has the 14mmCCW thread for common airsoft spec muzzle deceive. 
 
Same profile as the original steel version.
 
**For HAO L119A2 only. Not compatible with stock Marui MWS receiver.
 
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.
