Our take: SRC's performance aluminum 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.
SRC's aluminum air nozzle is an inexpensive upgrade part especially if you plan on using or already are using higher powered springs, as they provide maximum
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 SRC 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).
