What is a Fully Automatic Nerf Gun?

Fully automatic Nerf guns are battery-powered blasters that can fire ammo continuously. Just hold down the trigger and fire away. 

These blasters are also referred to as motorized or machine Nerf guns. An automatic Nerf gun uses an internal flywheel mechanism. Batteries power it.

When exploring my list of best Nerf Rival guns, it becomes evident that the blasters in this series prioritize high-performance gameplay.

Before you can start firing, the flywheel needs to be engaged. That happens via a separate acceleration trigger or a standard on/off button.

It is safe to say that the effectiveness of the internal flywheel mechanism plays a significant role in determining how well the auto Nerf gun shoots.

When it comes to choosing the best Nerf machine gun, the internal flywheel mechanism is a crucial factor to consider. It determines the effectiveness and accuracy of the blaster’s firing mechanism.

Fully automatic Nerf guns use an internal flywheel mechanism powered by batteries, allowing for continuous firing with just the pull of the trigger. So, make sure to choose a machine Nerf gun with a reliable and efficient flywheel system for the best performance on the battlefield.

Factors to Consider When Buying a Fully Automatic Nerf Gun

Choosing a fully automatic Nerf gun can be challenging. However, to make that choice easier, we’ve devised a list of things to consider when you want to pick one.

Rate of Fire per Second

When evaluating the performance of a full-auto Nerf gun, one factor to consider is the number of shots it is capable of firing per second. In this respect, Nerf has made significant advancements.

Back in the day, it was considered exceptional quality if a blaster could hit two or three darts in a single second. However, people have significantly higher expectations, and the Rival series is primarily to blame for this development.

For instance, the Rival Nemesis can fire five bullets per second, while the Rival Prometheus can fire an astounding eight rounds. Wow!

Shooting Capacity

Since these blasters can fire rapidly, would you run out of ammunition just as quickly?

Yeah, and this fact brings up yet another aspect of a new fully automatic Nerf pistol that you should consider before purchasing: the shooting capacity.

You will discover that most full-auto Nerf blasters have a sizable magazine in the package. It would help if you did this since, in the absence of it, the shooting would be over in a few short seconds.

However, a significant gap exists between a magazine that can hold 20 rounds and one that can hold 200 rounds. The Prometheus, for instance, has an incredible capacity of 200 High-Impact rounds in its magazine. Nonetheless, at a rate of eight rounds per second, you’ll be out in 25 seconds.

The capacity of the Nemesis is 100 rounds, which is also very generous. This will allow you to keep firing for about a minute before reloading the weapon.

Batteries 

The fact that Nerf machine guns require batteries is easily the brand’s glaring shortcoming. In addition, they often consume much of the battery’s power.

Because of this, it is essential to determine how many batteries they require and ensure that the batteries you purchase are of high quality and can serve the device for an extended period.

It is important to note that the Prometheus, for example, comes with a rechargeable battery, which is far more efficient than a set of standard batteries and weighs less than a set of regular batteries.

Age Check

Nerfing is meant to be a joyful activity that even young children can participate in. However, keep in mind that we are discussing fully automated nerf guns.

These are, without a doubt, incredibly potent in their own right. Something of this magnitude carries a high danger of causing potential harm to players younger than the age recommended for participation.

It would help to look at the model’s age restrictions before using it. If you are getting it for a child who is only 8 years old, you should not get a model that says it is best for people 14 or older.

Type of Darts

When purchasing an automated Nerf gun, it is recommended that you also buy the ammunition separately. Also, most Nerf gun models come with a list of preferred dart types and official versions of these darts.

In the best-case scenario, you should still examine the type of dart because there are times when the dart or ammo that a gun utilizes is the source of the problem.

The player may have a particular type of ammunition that makes it difficult to manage. In this scenario, if you want to avoid purchasing an automatic blaster compatible with a dart type, you need more confidence in playing with it.

Additionally, the overall performance will be determined by how well the blaster is designed and by the darts that will be compatible with it. This is because the blaster and darts will work together.

Safety Tips for Using Fully Automatic Nerf Guns

1. Appropriate eye protection

When using fully automatic Nerf guns, it’s essential to wear appropriate eye protection to prevent injuries from stray foam darts. Ensure that all players, both children, and adults, wear safety goggles or glasses designed for foam blaster activities.

2. Adhering to game rules and guidelines

Establish and adhere to game rules and guidelines to ensure everyone’s safety during foam battles. Set boundaries, define safe play areas, and establish rules regarding where and when to fire the blasters. Encourage fair play and make sure all participants understand and follow the rules.

3. Proper maintenance and storage

Taking care of your fully automatic Nerf gun is crucial for maintaining its performance and safety. Regularly check your blaster for any signs of wear or damage and address any issues promptly. Store your blasters and ammunition in a cool, dry place to prevent deterioration and ensure they are ready for your next foam battle.

4. Teaching responsible use and sportsmanship

Teach players, especially children, the importance of responsible use and good sportsmanship when using fully automatic Nerf guns. Encourage them to respect other players, avoid aiming at the face or sensitive areas, and always prioritize safety during gameplay.

Frequently Asked Questions

Should You Wear Protective Gear?

To ensure safety during Nerf battles, always wear appropriate protective eyewear, especially when using powerful and fully automatic Nerf guns. Practicing proper safety measures, including eye protection, is crucial for a safe and enjoyable experience.

Are Automatic Nerf Guns Noisy?

While most Nerf guns produce minimal noise, some powerful automatic models have motors that emit loud sounds. Although this noise may not bother neighbors, players on both teams might find it annoying. However, the whirring sound of motorized blasters is an inevitable trade-off for the rapid acceleration they provide.

Are the automatic blasters that load from the back superior to the ones that load from the front?

If the blaster you’re referring to requires a quick reload, this option might be decent. Since once the loading process in the back section is over, the player will have an easier time with things overall. Loading in the back takes less time when facing the player, so this configuration is preferred.

Are Automatic Blasters Powered by Rechargeable Batteries better than Traditionally Powered Counterparts?

The need for additional power in high-firepower blasters, such as those firing 8 rounds per second, makes rechargeable battery packs a more user-friendly option. Frequent replacement of regular batteries may prove to be expensive, so rechargeable alternatives offer a cost-effective solution.
