Element Airsoft P90 AEG Air Nozzle w/ Internal O-Ring

Your gearbox can have a heavy spring and still shoot soft if the air seal leaks. The air seal is the sum of the piston head O-ring, the cylinder head O-ring, and the nozzle — and if any one of them lets air escape, you lose velocity and consistency. The Element air nozzle closes that gap.

Many stock nozzles ship without an internal O-ring, which means compressed air leaks past the cylinder head instead of pushing the BB. This one has the O-ring built in. It improves the seal without adding stress to the piston or gears the way a heavier spring does. If your factory nozzle already seals well, the difference is smaller. A leaking stock nozzle is where you notice it most.

Cut specifically for P90 and E90 metal gearboxes. The V6 shell uses its own cylinder and nozzle shape, and parts don't overlap with the V2 or V3 ecosystems, so a P90 upgrade path is narrower than most. Element is the one that fits.

Drop-in replacement — split the gearbox, swap the nozzle, reassemble. No special tools beyond what you'd use for any internal work.
