Spudgun stock.

[Bias_P11]

Here's how I would have gone about it, with the High Standard HS-10 in mind:

- full length suppressor packed with steel wool

- compact bullpup configuration, maximum barrel length for minimum overall length

- fancy AR ignitor grip from USG

- smaller chamber:barrel volume ratio to keep power up and a quiet shot - have a look at this data from Burnt Latke's excellent site.

You can buy a cheap airsoft shotgun and hack the body up for parts like buttstock and pistol grip.

Its not visible, but my gun is a breech loader and the barrel is removable. The Supressor could be improved with a a steel wool alternative (I bought a scrubber thinking it was steel wool, but it was actually some sort of fireproof fiberglass and polymer composite). Interesting data though.
