Tomo of PDI/X-Fire sent in news about their upcoming Modular Stock for the VSR-10 series. The stock is all CNC machined and you can use any slide stock and grip. The grip is set at GBB size so it'll be more realistic. Expected release will be mid-September but pricing will be announced at X-Fire soon. It'll be on display at the Paris SGS Show which will be on the 7th to the 9th of September
