I've got a marauder (or nomad I guess) as well as an SR-22 and the marauder kit is by far much lighter. I haven't put them on the scale but in your hands it feels like half the weight. That being said the stock 10/22 is pretty dam light. If you really want to go all out why not try modifying a synthetic 10/22 stock. They're pretty light to begin with and come with the picatinny mount for the top. From there I'm sure you could shave weight from a lot of places and shape the stock to what your looking for.
What did you end up choosing?
