Valor Airsoft - MrRJC shows the custom work done with the GHK Gas Blowback Conversion Kit... "This project has been on the backburner for sometime now. After finding a random eBay listing for a GHK AEG to GBBR conversion kit we've wanted to find time to make this conversion. In order to make the conversion more reliable (and useable) we were inspired by Explosive Enterprises high cap GBBR mag design to make a HPA set up to get the most use out of this and it was certainly worth it. 

These kits are hard to find so if you find one (for cheap) consider it!"
