I took ideas from that, some 50bmg rifles, and SKAT. I was originally going to make the stock solid and house a CO2 rig but I turned away from it because of design and looks. I have also figured out if I want to do something internal I have room inside the suppressor to build something.
Bullpup Sniper Design
Here's my little project I've been designing for about a year now. CAD design is near complete so machining will start very soon. Everything except the scope has been designed one off. 509mm inner barrel length in a 30" overall length. Custom hop up design using vsr buckings and barrels. Open to thoughts and criticism!!

Yeah so I know it's confusing to look at because the bolt and knocker surround the hop-up unit but here it is by itself. When the bolt is pulled all the way back it hits the cycle nozzle(brown) and allows a feed. The bolt will catch back forward just past where the cycle nozzle meets up with the bucking. I wanted to make the most solid setup possible and I figured a moving nozzle wouldn't be ideal when firing. This way nothing moves when firing. The red rod is a detent so the nub cannot spin. Metal U channel nub. 2 piece hop-up chamber(teal/purple). Air from the valve in the back comes up through the tube(purple) when the knocker hits the valve.
