RAS FIX Scope Riser Mount

The RAS rail system on the real firearms is fixed on by via gas tube.
AEGs don't have gas tubes to connect both RAS and upper receiver.
RAS FIX is a new product which mounts on both the upper receiver and RAS. It will make your RAS and upper receiver connected tightly.
It can also be used as a scope riser mount.

Our Gemtech TALON system may need this item.
