I just found this chasis by Taccom
https://taccom3g.com/product/ulw-cha...er-10-22-22lr/
I'm seriously thinking about getting one for my iron sight 10/22 because the chasis by itself is only 12.2oz which is crazy light; it will end up a bit heavier once you factor in the pistol grip, stock tube and stock.
Interesting it takes a standard AR buffer tube but you can get their stock with it with the shortest LOP being 10.375"
