First:
I would prefer the pistol grip to be canted with the lower end further forward than the top end.
Second:
I would prefer a bullpup, for easier use getting in and out of vehicles, or around the house
Third:
I would prefer a delayed blowback: no gas tube to blow, no piston to kink. No sudden impacts from things slapping around.
Fourth:
I would prefer a quick change barrel, and would like to be able to change calibers by change of barrel and magazine.
Fifth:
I would prefer to have two magazines, and have the ejection path straight down between them, with a switch that when one magazine emptied would switch feed to the full magazine. That way I could feed from a full magazine while having time to change the empty one.
I suppose you would prefer to have someone carry that fifteen pound beast you’re imagining, too?

They only delayed blowback I know of handling rifle power rounds is the roller system of the Cetme/HK design and MG42/MG-3. To have the 7.62 Nato round operate straight blowback like an UZI, the bolt would have to weigh about 30 lbs.
Nice tagline, it reminds me of mine.
