What are the most common ...

Only option system I've used is the one with the beam sabers... Even has some eyes on it, good set! Dunno if I actually used any of the sabers... >.< Forgot over the years, but some are off the sprue

Yes, I use them quiet a bit on my Models, both ranges are good and also include poly-caps which come in handy when the kit supplied ones are missing or been damaged.

Even went so far as to buy the Wave guide to their option system which has plenty of ideas on how to use them in imaginative ways.

Tends to get a bit pricey though if you rely too much on them.

I see. It looks like a useful line of detail parts.

They are clear parts made by Wave(Japan) and are designed to be used for sci-Fi kits. They come in a selection of shapes, sizes and colors.

They are part of Waves and Kotobukiya's range of super-detailing options for robot kits, the full series contains everything from hands to exhaust nozzles, joints, rivets and also springs, etc.

Some of the parts can also be used for standard models like airplanes to replace molded wing-tip lights and so on.

Got a big drawer full of the stuff.

Cut open vents & what not and add brass screen. Seem to be doing it to just about anything with a intake.

I also have started turning barrels to repace the cheesy, mis-formed ones that normally come with armed kits.
