This amazing combo set for the WE M4 GBBR features the:
-RA Tech M4 Forged Receiver:
The WE M4 GBBR receiver doesn't have much when it comes to markings or style but the RA Tech M4 Forged Receiver with AAC markings is going to change all of that. The quality is similar to Inokatsu and Viper Tech which means that it is very close to the quality of the real steel version. The texture is smooth and the markings are both making this the perfect receiver replacement for the WE M4 GBBR.
-And the SVOBODA AAC 300 Black Out:
The SVOBODA AAC 300 Black Out is made specifically for the WE GBB. The Keymod series of rails have been increasingly popular these past months as it allows the user to add rails in where they want for all the accessories they need. There are also 2 holes for sling point mounts as well.
And the New Age M4 Steel Receiver Pin & Forward Assist, making sure you have the most decked out WE M4 GBB out there.
