This was just released last Wednesday by MadBull Airsoft and now it is available at Jag Precision, which is an authorised distributor of MadBull products in the USA. This is the fix you will need for your RAS rails as the lack of gas tubes in AEGs may twist and turn your front rails from the receiver body. This fix keeps both parts in place and a peace of mind for the airsoft player... "One of the best design for Airsoft players! Available now in USA. Distributed by JAG Precision.  Please contact your local dealers for details."
