Fusion Engine Nozzle AK
All drop in Fusion Engines come with the Blue Nozzle, which outputs anywhere from 380 to 435 FPS with .20g BBs at max input pressure of 120psi depending on barrel length, brand, etc.
The muzzle velocity with a given nozzle is partially determined by the length of the barrel therefore the examples below are approximated FPS for reference when using an M4 carbine length barrel (363-375mm) with .20g BBs at the max input pressure of 120psi. An M16 rifle length barrel (509mm) will bump this up by an average of 30-40fps.

Green - 325fps
Gold - 366fps
Blue - 405fps
Silver - 494fps
Red - 550fps

While the sport of Airsoft is designed to be enjoyed by all ages, ignoring proper safety practices can turn a day of fun into a tragedy. Todays modern airsoft guns are capable of firing a BB at velocities that can and will penetrate fabric and skin, causing serious injury. Always wear "Full Seal" eye protection and observe proper weapon handling practices such as keeping the weapon on "safe" and cleared with the magazine out to prevent accidental discharge. REMEMBER!! Safety begins with the shooter!!
