CYMA MP5K Hop Up Research

[Sacarathe]

I'm having some difficulty researching after market hop up units for my new gun. Can anyone give me any pointers to make the efforts go something above 100% failure , unfortunately most of the research is searching forums and retailers, but its often not clear if an item would be usable.

 

Also, what gun, if any, is the CYMA MP5KPDW (CM.041PDW) a clone of?

 

Should have researched before buying, but I've chosen all my other upgrades, including the barrel (orga wide), only the hop remains.

Last time I check the CM MP5K's Like most CM guns are clones on TM. Maybe you could try using a Tm hop http://www.tokyo-model.com.hk/shop/tokyo-marui-mp5k-original-hop-up-chamber-p-2150.html
