Well keep in mind Magna system innovation right now is left with two manufacture:
VFC- hk416, SCAR
GHK- KAC PDW
The biggest problem with the gbbr is simply, the availability of the gas mag. If it was available in the form of SR25, Im sure it wouldnt be long before the market becomes saturated with 7.62AR. However, I failed to see the point as most people hate the dynamic of the gas vaporization. (aka fps change)
