    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.

    Easy installation
    nozzle swap
    upgrades are simple, and also inexpensive

    can't change trigger

    Why I gave 3 stars is because I didn't receive a bucking with my engine, as said in the description. And I hate dealing with Evike's customer service.

    "So, after hearing so much negative things about the Valken V12, I bought one. When It came in the mail, I installed in in my Vfc Hk416. It fit snugly, and I took it out to shoot right after. With the stock hop up and barrel, I got about 200ft of range and pretty good accuracy. Now, 3 years later the V12 has preformed amazing. I installed a v12 red nozzle, and a Lightning banjo. Also I put in some poppet shims. Now, my air efficiency is BETTER than my Wolverine SMP! On a 3000psi tank, I get almost 5000 shots. After the gun was flat hopped and tuned, it was getting unparalleled accuracy and range. The durability of the v12 is on par with the Polarstar Gen 3 FE. It has compatible internals with the FE gen 3, save the FCU. For the Pro's of the system, I will say one thing, I can only think of one Con. Which is simply that it was harder to tune than my Smp, and took a while. After owning the v12 for some time, it is safe to say that i would have payed the $449 price tag that the Valken v12 was released with.
