Wouldn't reccomend single regging with an angel air myself, I tried it with my LCD angel I'd go on the field shooting around 280 fps and come off around 240 fps. Also the Air I found it hard to get the velocity adjustment just right, it was either 280 or over 300.
hmm, just a thought but you say your running Co2 with a vert maxflow...Would it be easier to buy a screw in 4.5k air system and not bother with the voodoo foregrip? Would work out cheaper and you could always switch back to Co2 if you needed to
i have already bought the angel air so if it dosent play i could always change to a maxflow. this whole problem did not even occur to me til after i bought it, wish id asked sooner i would of just gone for a maxflow.
