HAO's G Style SMR Rail For HK416/MR556 . Sick of the poor quality of the cheap replica?HAO's G Style SMR is 100% made with every detail as same as what it should be.
All the handguard body for every option is the same. The difference between the options is that we made different barrel nuts for each brand of airsoft HK416.
 
VFC/HAO user can use their stock barrel nut directly so there's no barrel nut that comes with the order, please be noted.
 
Our complimentary segments(Long*1 Short *2) are free without any additional charge.

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.
