GHK AK Hop Up unit
 

Hey all,

Anyone have any idea which hop up unit (metal) will fit into the GHK AKM? I just tried the Maple Leaf version from Red Wolf, and it doesn't fit at all (not with the plastic cover that was over the original version).

Thanks,

Mausturm

TNT or GBL units are your best bet, but they require a new inner barrel as well. They work off of buckings similar to a VSR, so they tend to be more accurate/consistent.

Curiosity sake, what would be a good inner barrel to pair with The GBL Hop Up if I were to go with that? I'm not familiar with VSR Inner Barrels at all, so any direction would be appreciated.
