Help pls ~~ Water Sniper Cosplay

Hey ppl, I want to build a custom water gun sniper for cosplay and got the aesthetics thought out. I'm now stuck at the "engineering" part of the water shooting mechanism because i just don't know anything about the topic. To go into more detail, I asked gpt about this and recommended me a small 12v diaphragm pump that feeds a pressure tank through a check valve. Pressure/water being released by trigger pull and a super fast magnetic valve. That all sounds very logical to me but I just can't make sense of how to go about it. Is this like actually a good way of doing this? I don't know if my requirements are delulu or if I can actually do this 5+ meter range Single "bullet" water burst on trigger pull Not too loud All compact to fit inside the sniper (The sniper in question will be a modified barrett mead mk22). Like does this all make sense, does anyone know how to go about this? Please help T.T I only built aesthetic cosplays before and this one is just way over my head right now. Thank u submitted by
