You can't put a DSG on an M16 length barrel.
Frank, as much as I respect your input in most cases, your statement here is simply not true.

I've built a 70 RPS capable gun that shot at 370 FPS. I also game guns that can do 50 RPS at 345 FPS, and 36 RPS at 425 FPS on little buffer tube batteries. You can easily do a lot more with a brick battery.

As for the OP

-You do NOT need a DSG. There is no benefit in building a DSG unless you're going for 50 RPS or more, and even then a SSG is more power efficient.

-PicoSSR is a piece of shit. You're going to be drawing 35-40A if not more on that setup, you'll need a 3034 based FET if you want it to be reliable.

-Do not use a hard flat hop. They cause jams and don't hop any better. Use a soft rubber with a hard nub.

-MadBull pistons are garbage. The plastic they use is not strong at all, and cannot take much before the rack is sheared out the back. Use a Lonex piston.

-Don't use a SHS nozzle, they are slightly off spec being half a mm too long. The stock G&P nozzle is great.

-The ONLY gear set that will be reliable in that kind of stress is Siegetek. I've NEVER seen them break in even the most stressful setups. I've run them up to 70 RPS. The ONLY time I've ever seen them break is from grossly incompetent user error.

-If you haven't gotten this already, pretty much none of the components you listed are going to work in the setup you are trying to run.

If you are using a brick 11.1, then your goal is easily achievable if built properly.

Your basic setup will need to be
-Siegetek 10:1 Gen2 gears, make sure its Gen 2 otherwise you may run into feeding issues.
-Lonex or Retro Arms piston, lightened
-Tienly 35K motor, 45K will give you close to 50 RPS but will be inefficient and cause extreme motor heat
-POM piston head of some sort, I use Lonex, Prometheus and Retro Arms.
-M120 spring. M120 with a perfect air seal should net you just over 450 FPS.
