KJW pistols have never let me down.
I'm probably one of the few canadian owner of a FMU 2009 JG HK416. This thing is a beast, they've improved their quality a lot.
So is my Cyma AKS74U. Shakal is right, it's the energizer bunny of AEGs.
I'm not sold on a particular brand, I've seen lemons in all of them, including TM. And I was not impressed by KSC' System 7.
