Whack a zombat flash hider on a custom cut down 1"ris...What's not to love? Have two on one point bungee slings, have them secured to a vest on quick release buckles, hit it when ready and spray away! If someone did that and could use them effectively, props and creds to them.
Ah, but the "dream CQB weapon" kinda suggested practicality. Never mind, if thats your thing. I was also just commenting on the general repeated mistake of a folding stock being good for CQB.
I don't think he's referring to the weight, which you are mostly correct on, but having the stock in your shoulder significantly increases the pointability. Imagine firing a P90 without the stock!
Stockless is overrated for CQB. What control do you have over the weapon after removing the one important point of contact to your body? Front wiring is cool, but at least invest in one of those tiny retractable stocks that make it small but easy to aim and fold up like the AAC Honey Badger stock.
