Ambi Fire Selector Gear Set for M4/M16 Replicas [Arcturus]

I'm only going to be giving 3 out of the possible 5 starts because these kits, though they seem to be well put together are missing 2 key components. These parts do look to be of good quality, but without having the actual style of switch that they interact with come in the kit with it, it becomes a juggling act to find the ones that line up and screw in correctly. The second component that is missing from this kit is the selector plate that will mesh up and align correctly. To many times I have tried getting what appears to be a plate that looks close to fitting and working, fail shortly after reassembling the gearbox with the outer shell body.
