Our take: 5KU's performance air seal nozzle is a great, inexpensive way to upgrade your AEG's performance. Performance air nozzles allow for better air compression, ultimately leading to more power for your AEG. Typically, doing an air seal nozzle replacement/upgrade, using a performance part such as this one, will allow for an increase of 10-30 FPS in shooting performance.

For reference, many stock AEGs come with air nozzles that do not include an O-Ring to enhance compression, thus resulting in a loss of compression and subsequently a loss of power. This 5KU performance air nozzle does utilize an O-Ring, and thus with installation organically increases power without causing more wear and tear (like many other power upgrades do).

As with all internal Airsoft upgrades, professional installation is highly recommended. Airsoft Megastore is not responsible for any problems that may occur when installing this factory upgrade part.

Compatibility: Fits (most) M5/ MP5 Version 2 metal gearbox AEGs

4 5KU Airsoft Upgrade Air Seal Nozzle - For M5 / MP5 Metal Gearbox AEGs *****
Good replacement part

"Installed on a Classic Army B&T MP5. No feeding issues or problems yet. Since I have an non-linear spring, I cannot measure if its compression is solid through a chrono. Overall, a good replacement for a cracked nozzle."

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
