Make sure you check out our entire selection, and do your research to find the perfect choice for you! Essentially, these tiny little components are used to control the ebb and flow of electricity inside of your airsoft gun. Combine that with the inherent function of most MOSFETs to read and regulate your electrical, and the GATE can help you troubleshoot your gun when you have an issue too! Give our customer service team a call and they can fill you in on all of the information! It also should go without saying, but well mention it here anyway: If you dont know what you are doing inside of a gearbox, installing a MOSFET or ETU is definitely more complicated than other tech work for a new airsmith. Older systems use mechanical switches, which are easier to install and get set up, but because they have to make contact with something they are prone to failure over time. By accessing the Site, you certify that you are older than 18 years of age or the age of majority where you live, whichever is older; that you are the owner of any credit card used to purchase on items on the Site; that you are familiar with all local laws in your area affecting your legal right to access airsoft products; that any products you buy are for your own private enjoyment and that you will NEVER share these products with a minor in ANY WAY. MOSFETs are a curious little device in most airsoft guns, and their name can be a bit misleading. This is a big trend in ETUs as it prevents premature part wear. Well, the secret to both of those things, as well as commanding complete control over super high performance builds like DSGs and snappy DMR set ups is all in this little system called a MOSFET (or as youll see more advanced versions called; an Electronic Trigger Unit or ETU for short) that manages your electrical signals and tells your gun how to handle business! Well, essentially, the ETU is an advanced version of an Airsoft Mosfet chip.

If you can fit the wires, these will typically work with your gun.

Be ready for that ahead of time and plan to put the work on a trained local airsmith or utilize our Airsoft GI Tech services.

Youve got our picks for the top MOSFETS and ETUs on the Airsoft GI website, but we offer much more than the four models weve featured here! Any person who changes, alters, removes, or obliterates any coloration or markings that are required for by any applicable state or federal law or regulation, for any imitation firearm (replica firearm), or device in any way that makes the imitation firearm (replica firearm) or device look more like a firearm is guilty of violating the state or federal law. This unit even features Binary, which is a more rare feature to find on these sorts of chips. All airsoft guns are required to have the tip (1/4 inch) of the barrel permanently colored in blaze orange.

The Zion Arms Nebula ETU is a new comer to the aftermarket scene, but its been making waves since it first released as the de-facto trigger in the Lancer Tactical Gen3 rifles. A significant amount of this is because you lose out on some of the stat-tracking and troubleshooting capabilities of the Titan, but you get a majority of the performance benefits. We cant stress enough the importance of getting a professional to do the install for you if you do not feel capable. Obviously, we have some products we prefer over others here at Airsoft GI. Things like the GATE Titan, Jefftron Leviathan, or Zion Arms Nebula fall into this category. All of these chips are capable of so much more than a simple AB mosfet by giving you the ability to do things like set your full auto setting to burst fire or binary modes. Since this system cant read the exact position of your gears, it does it with a lot of fancy math and data from your electrical signal, so its a little less exact than an ETU, but at the cheapest option on this list, you cant beat it! What about that ETU? They are essentially the building block of modern electronics and youll actually find them in everything from basically anything that handles electric current nowadays. Overall, this pint sized upgrade piece is one of the most versatile options you can buy, but that comes with the downside of a more difficult install and a higher price. Where a traditional MOSFET would be installed in the wire harness of your circuit to do basic things like manage your electrical distribution and speed up the stop/start process of your motor, an ETU is capable of much cooler things. This gear has a magnet embedded inside of it that the chip can read to determine the cycle of your gearbox and attenuate your electric currents accordingly. Read up on the features, and dont judge on the title alone when youre shopping for your upgrades. The sensors in the PERUN dont touch anything, so theyll last a lot longer, and thats a great point in the reason to buy column. We can even install it for you in your gun as well. Lets get into the specific products were big fans of here, and why we like them! The AB++ is a great choice because it offers more electrical liability thanks to its unique digital fuse, works on a ton of different models of airsoft gun, and can even give you burst fire. To determine which one is right for you, youll need to figure out which features are important, and what you are willing to spend. MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor.

This premium trigger packs a lot of the user functionality you want in an ETU, but skips out on a lot of the fussier sensors and stat tracking data to keep cost down and reliability up. Essentially, any time you see a full trigger unit swap that can do a lot more than passively regulate electric current, youre looking at an ETU. It is intensely customizable, offers incredible protection for your gun, and has the option to transmit data through a connectivity cable or Bluetooth addon that allows you to pull stats and metrics off of your airsoft gun to help you fine tune it. If you dont need the majority of the features on the ETUs weve featured above, an on-wire MOSFET is the option for you! No person may openly display or expose any imitation firearm (replica firearm), in a public place. The ETU (or Electronic Trigger Unit) is to the basic MOSFET chip what a whole computer is to a simple transistor. It is estimated that there are over 13 sextillion (thats 13,000,000,000,000,000,000,000 for you numbers people) MOSFETs that have been manufactured since their invention in 1959 by Mohamed Atalla and Dawon Kahng.

This is their primary reason for being installed in airsoft guns, especially high performance setups, as it maintains battery efficiency and stops you from blowing up more sensitive or expensive components like your batteries and motor, or burning out your trigger switch. It also gives you the benefit of lightning quick trigger response and programmable fire selector options like with the Titan and the Perun. Have you ever wished for burst fire or a binary trigger? Most products advertised as MOSFETs in the airsoft world arent actually a single MOSFET device, but a chip containing a few different components of which the MOSFET (sometimes more than one) is the main component. Have you ever wished you had more control over your airsoft gun? The GATE Titan is one of the most famous names in the ETU world.

The PERUN is a unique offering as well. How is that different from a MOSFET? They are also great for non-standard gearboxes, as they are less reliant on the actual gearbox shells dimensions since they exist outside of it. It uses high tech photo-optic sensors to read your gears, which means the chip always knows exactly what your gun is supposed to be doing. The term "public place" means an area open to the public or exposed to public view and includes streets, sidewalks, bridges, alleys, plazas, parks, driveways, parking lots, automobiles, whether moving or not, and buildings open to the general public, including those that serve food or drink, or provide entertainment, and the doorways and entrances to buildings or dwellings and the grounds enclosing them. If your electrical system was something like a water pipe, these would be the sensors that allow your pipes to adjust and not over-flood or burst with too much power. The PERUN V2 also runs on photo-optic sensors to take readings on your gearbox and manage your function. You may encounter some soldering, and almost all of the MOSFETs and ETUs on the market require a a full tear down of the gearbox. The Nebula uses a special gear included with the Trigger replacement chip. Thats enough science for now though, we know you didnt come here for a thesis paper on modern electronics. It utilizes multiple mosfets and other components to give you more control over your airsoft gun. You may also see them called an ECS (Electronic Control System) or misleadingly called a MOSFET as well. It provides much of the same functionality as the GATE Titan, but at a much lower price point. ETUs are the types of chips youd find that replace your entire trigger unit. These units still need to be soldered into your trigger and wiring, but they can provide some of the basic functions of an ETU without most of the cost.
