Plenum Size Does Matter !!

I think it’s time to upgrade the MROD then!

Or just develop and design a collapsing internal plenum that acts like a plenum that is between 2-4x larger. (depends on design of plenum and your guns discharge of air).

Say you have a 10 cc plenum, and your shot releases 5cc of air, if you collapse your plenum 50% during the shot, well it's as if you doubled your plenum to 20cc! If you had a shot take 7.5cc and that plenum could collapse 75%, you'd replicate a 40 cc plenum!
