(Discontinued) 

Hephaestus's Charging System is of a aluminium construction which is very lightweight and is suitable for GHK AK GBB Rifle Series except the AKS-74UN and AKMSU. It replaces the original Gas Tube so the charging handle is at the front making it a lot easier for right handed shooters so you don't have to swing your arm around to pull the charging handle back or release your right hand to pull it back. But the original charging handle is still there if you wish to use that instead.

It comes with a 4 Inch rail attachment which fits along the top of the rifle so you can add any accessories you wish!
