GHK 50rd Gas Blowback Magazine for GKS74U Airsoft GBB Rifles

1 Customer Review

by Shawn F. on 12/01/2013
"Bought 4 of these. The magazine holds up on green gas/propane at 70 degrees Fahrenheit with zero leaks.. These are a pain in the behind to load with BBs. Modification is needed on the feed lips of the mag so it can be loaded with ease. A circular file or a totary tool with the proper bit will do the trick. The opening on the feed lips just need to be opened up a little bit. Holds 48 rounds. Samoon recomends that magazines should only be charged for about 6 seconds and that putting gas in it for longer than that may produce adverse effects.
