No stock, right. No foregrip handle allowed either, that would make it a class 3 AOW. However...
Here's it all tricked out. The mag is a little close to the pistol grip, but still makes for a fine place to put that leading hand. Holding it pushed out against the sling steadies it pretty well too.
Meant to say in the first post that it's gas-piston also.
Not meaning to step on your post, but here is a friend of mine latest project. This pic was posted on Calguns, so I beleive its ok to post. Your gas piston is pretty slick though.
