I have a Lost Nation VBS for an Anschütz 1827F but I also have other (more traditional wood based) styled stocks. I like the system overall and it makes use of a aluminium v-block style chassis rail. Other modern wood based stocks are essentially just as adjustable in all critical areas but typically cost significantly more. And then there's the likelihood that one would spend a couple thousand on a new stock and then take drills, dremels, saws and wood-filler to further customise it... or go full custom stock.
The standard cheek piece is ok and really you don't need a lot, but rather a simple hard reference point made of delrin. The pro cheek piece has a wider flat surface and added lateral adjustability. The "buttplate" comes with rubber grip insert rather than cushion, but we're talking about .22LR, a rubber cushion would be irrelevant and a nuisance for biathlon.
The pictures shown above are older prototype and earlier versions of the bits. The chassis has remained more or less the same, but the latest version has different pro prone handstop, grip designs, butt hooks, etc.
Ethan Dreissgacker is a solid guy and makes the VBS for numerous clubs including members of the US national teams (incl his sister), along with some other nation athletes on the IBU World Cup).
