Our take: Element's performance air 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 nozzle replacement/upgrade, using a performance part such as this one, will allow for an increase of 10-40 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 Element 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).
