Clear, may give away position in woods.
I got this for smaller and lighter play as well as ammo conservation. I prefer it mostly on pump markers such as my brute as you wont use all that much ammo anyways. I taped mine up black with hockey tape so its harder to see in the woods then the clear plastic. I think it works great and with the types of markers you will use it in they have blow back or shaking form the pumping so jamming is never a problem (and theres no point in using a 50 rd hopper if your going to eb shooting 7 balls a second anyways.
Great for snipers expecially if using pump markers. if you shoot alot forget it.
