Pretty much every major airsoft company makes some great standout replicas and then some other shit ones too. There's not much consistency in the market. I blame that on the total reliance on Asian manufacturers with (relatively) poor quality standards.
voodoo, I've got a couple KAC grips and may end up going back to those. I've had this CQD for awhile and never got around to trying it out, so I'm gonna use it a bit before I go back. The KAC is significantly lighter.
