If one were willing to buy a hopper that wasn't made by VL (PB fashion being what it is I know it may not be in vogue, but hear me out), you could get a Ricochet Apache loader that'll feed 15 no problem and weighs probably no more than a Revvy. My friend has one and it makes my HALO B feel like a brick, and it'll keep pace an Egg no problem.Yea but eggs look gay! If you could make a loader with the body of the revvy and a decent bit of performance then it would sell like hot cakes!
