Nuprol Aluminum Air Seal Nozzle for N39 Series Airsoft AEG Rifle – Blue
If you're looking to upgrade your N39 or M4-style AEG for better consistency and FPS output, the Nuprol Aluminum Air Seal Nozzle in Blue is a must-have component. Precision CNC-machined from lightweight aluminium, this nozzle features a non-corrosive anodised finish and comes pre-lubricated for smoother installation and longer-lasting performance.
Fitted with an internal O-ring, it ensures a tight seal between the cylinder head and the hop-up, improving air compression and shot-to-shot reliability. That tighter seal means more efficient air use and a boost in muzzle velocity—great for players chasing consistent power. With a precise 24.3mm length, it’s tailor-made for N39 series and compatible M4 AEG platforms.
As with all internal upgrades, proper gearbox knowledge is key—so if you're not confident, seek advice from a gun tech to avoid damaging your rifle. When done right, this upgrade makes a noticeable difference to your rifle's performance.
