Manufacturer: ARES

Adjustment Notice:
As a mechanically adjustable system, extreme settings can affect overall performance and may lead to irregular cycling. For best results, make small, incremental adjustments until the optimal balance between responsiveness and stability is achieved.

Disclaimer on High Pressure Air (HPA) Systems:
HPA Tanks are a safe and effective source of power though there are some precautions you must follow. Please follow these proper precautions when using HPA systems:
  • NEVER put oil in the fill valve of the tank, or else the tank can combust on refill and serious injury can occur. Lubrication is not necessary in HPA systems.
  • ONLY allow properly trained professionals to fill your HPA tank.
  • ALWAYS double check your Regulator pressure. Never raise the regulated pressure above 120 PSI.
  • Make sure to have your tank Hydro-Tested when necessary (Usually 3-5 years from date marked on tank, depending on make and model).
  • Be sure to properly transport your HPA tank. Store in a safe, secured place when in a vehicle, and be sure to stow in a bag or tank cover when in use. Avoid dropping the tank on hard surfaces as this can seriously damage the tank and lead to failure.
  • Always turn off the tank and bleed the air line when you are done. This will ensure a longer tank and system lifespan.

"For the price you can't beat it. I have dropped this engine into my gen 1 Am013 Honey badger from Ares with only needing to switch to a aftermarket hop up chamber. Currently running with the maxx m4 hop up chamber, nexus bucking and a tight bore barrel with 100mm more lenght than stock. With. 32s at 110psi this is easily a dmr. With a foam filled mock suppressor this engine is silent. Trigger does have slight dead space and is non adjustable, full auto rps is capped, a 48ci 4000psi tank will last roughly four 15min games or roughly 15 to 20 mid caps depending on bb cap per mag. Over all I've had no complaints for the price and no performance issues with 2 casual weekend games so far at my local airsoft parks.
