TacTopia Airsoft shows his MTW-9 build which he used carbon fibre to keep it lightweight... "After the Magpul upgrades, I wasn’t done. In this video, I take my Wolverine MTW-9 to the next level — swapping in a carbon fibre handguard, carbon outer barrel, and carbon stock tube to create the ultimate lightweight CQB beast!

Total weight saving: just under 500 grams lighter than stock — that’s nearly half a kilo off the front end! The balance shift is unreal — faster transitions, smoother movement, and insane handling in tight corners."
