What Is a Fully Automatic Nerf Gun?

Fully automatic Nerf guns, also known as motorized or machine Nerf guns, are blasters powered by batteries that can fire ammunition when the trigger is held down continuously.

The flywheel, powered by batteries, operates the firing mechanism when the trigger is continuously pressed.

The flywheel must be engaged before firing, usually through a separate acceleration trigger or a simple on/off button.

The performance of a full-auto Nerf gun depends on the efficiency of its internal flywheel system.

Rounds per Second

A way to evaluate the performance of a full-auto Nerf blaster is by considering its rate of fire, which has improved significantly over time.

A blaster that could shoot 2 or 3 darts per second was considered impressive in the past. However, with the Rival series, expectations for blaster performance have increased significantly.

If you have read my list of best Nerf Rival guns, you will know that blasters in that series prioritize performance.

The Rival Nemesis can fire five rounds per second, while the Rival Prometheus can fire eight.

Firing Capacity

If these blasters can fire rapidly, wouldn’t you quickly run out of ammunition?

Additionally, it is crucial to consider the firing capacity when purchasing a new fully automatic Nerf gun.

Most full-auto Nerf blasters have a large magazine, vital for sustained shooting.

However, a significant distinction exists between a capacity of 20 and 200 rounds. Take the Prometheus, for instance, which can hold 200 High-Impact rounds. Considering its rate of fire of eight rounds per second, having such a capacity becomes almost essential.

The Nemesis has a capacity of 100 rounds, allowing for sustained firing before reloading is required.


One potential drawback of Nerf machine guns is the requirement for batteries, which can often consume significant power.

It is essential to check the required number of batteries and ensure that high-quality batteries are chosen for long-lasting performance.

The Prometheus, for example, has a rechargeable battery that is lighter and more efficient than a set of regular batteries.

What About Semi-Automatic?

It should be noted that there are semi-automatic Nerf guns, which differ significantly from full-auto blasters.

Unlike fully automatic blasters, a semi-automatic Nerf gun has a single firing capability when pulling the trigger.

There are blasters available that have both semi-auto and full-auto capabilities. One example is the Nerf Pro Gelfire Mythic, which features a select-fire function for switching between semi and full-auto firing modes.

Top 7 Nerf Machine Guns

Here are my top seven fully automatic Nerf machine guns. These blasters are durable, impressive, strong, and provide a lot of enjoyment during battles.

1. Nerf Rival Nemesis MXVII-10K

Nerf Rival Nemesis MXVII-10K

The Nerf Rival Nemesis ranks high on the list of best Nerf guns ever produced. Many Nerf enthusiasts, including myself, appreciate the Nemesis for its numerous qualities.

The Nemesis was released in 2017 and was considered a revolutionary Nerf blaster. It was a large magazine with exceptional performance and a comfortable design, quickly making it popular among fans.

The Nemesis has a unique magazine called a hopper system, which allows for effortless loading of Rival High-Impact Rounds. The hopper pushes the rounds to the front of the blaster, making them ready to be fired.

Operating the Nemesis is a unique experience that many Nerf enthusiasts enjoy. The blaster is comfortable to hold, and its large magazine and excellent performance make it a top choice for those looking for a full-auto Nerf gun.

2. Nerf Rival Prometheus MXVIII-20K

Nerf Rival Prometheus MXVIII-20K

The Prometheus is a Rival blaster known for its exceptional performance compared to other Nerf blasters.

While it may be considered slightly extravagant, it provides a great deal of enjoyment. However, it should be noted that this blaster may not appeal to everyone.

Like the Nemesis, the Prometheus has a hopper-style magazine that is convenient and efficient. However, the Prometheus surpasses the Nemesis in terms of firing capacity, with a capacity of 200 High-Impact rounds.

The Prometheus surpasses the Nemesis in terms of rounds per second, achieving an impressive eight rounds per second with a fully loaded magazine.

The Prometheus must be held with both arms at the hip, which sets it apart from other Nerf blasters. Despite its weight, this fully automatic blaster offers a surprisingly ergonomic design.

3. Nerf Ultra Select

The Nerf Select is a fully automatic blaster in the Ultra Series, powered by flywheels and fed by a magazine. Although the Ultra series has not been very successful, the Ultra Select is considered one of the better blasters in that range.

Nerf Ultra Select

The Ultra blasters use Ultra darts, while the Nerf Ultra Select includes 10 Ultra darts and 10 AccuStrike Ultra darts.

The AccuStrike Ultra darts are designed to be more accurate than the original Ultra darts. In terms of performance, the firing velocity and distance of the Ultra Select are decent but not exceptional.

The Ultra Select has a small firing capacity of only ten darts per clip, which is a drawback compared to the Nemesis and the Prometheus.

However, the Select comes with two sets of magazines and darts simultaneously attached to the blaster. Loading the magazines and switching between them while using the blaster is simple.

Year: 2021
Series: Ultra
Ammunition: Ultra Darts
Firing capacity: 10
Batteries: 6 C-batteries

4. Nerf N-Strike Mega Mastodon

Nerf N-Strike Mega Mastodon

The N-Strike Mega Mastodon is a fully automatic, flywheel-powered blaster with an integrated dart drum that can hold 24 darts.

This blaster is one of the most giant Nerf guns ever made, and for that reason alone, it deserves to be part of your collection.

The Mastodon requires six D-batteries to operate, which adds noticeable weight to the weapon.

It has a firing capacity of 24 darts, which is generous but not as much as some fully automatic Nerf guns.

However, the Mastodon is considered one of the top-performing Nerf Mega blasters and provides an enjoyable shooting experience.

Based on the image, the Mastodon should be held at the hip using the handle at the top for added enjoyment.

Overall, the Mastodon is a high-performing blaster with an attractive appearance.

Series: Mega
Ammunition: Mega Darts

5. Nerf Rival Perses MXIX-5000

Nerf Rival Perses MXIX-5000

The third Rival blaster on this list is the Perses. It is a compact flywheel and conveyor blaster that can fire 50 High-impact rounds. The Purses also features a hopper system that functions well without any jams or malfunctions.

The Perses has a compact, comfortable, and lightweight design, which sets it apart from the Nemesis and the Prometheus. Additionally, it boasts excellent performance with a smooth and fast firing mechanism.

The Perses blaster in the Rival series features a primary trigger, trigger lock, acceleration trigger, and hopper, allowing for a satisfactory fire and firing velocity rate.

The Perses is a highly efficient and compact fully automatic Nerf blaster, making it an excellent option for those seeking high performance.

6. Nerf Hyper Mach-100

Nerf Hyper Mach-100

After careful consideration, I have included the Nerf Hyper Mach-100 on the list of best Nerf machine guns, as it deserves a spot.

The Nerf Hyper series has received mixed reviews from Nerf fans, and I have a moderate opinion of it. The Nerf Hyper Mach-100 is one of my favorites among the Hyper series blasters.

Blasters in the Hyper series, like Rival, use rounds, but they are smaller. Hyperblasters are not as accurate as Rival blasters.

The Mach-100 is the Hyper version of the Rival Perses but doesn’t perform as well. Some may argue that the Mach-100 is more suitable for kids.

The Hyper Mach-100 offers a range of features, including an integrated hopper with a capacity of 100 Hyper rounds. While firing with the Mach-100 is enjoyable, it may not provide the most ergonomic experience.

Year: 2021
Series: Hyper
Ammunition: Hyper Rounds
Firing capacity: 100
Batteries: 6 D-batteries

7. Nerf N-Strike Modulus Regulator

Nerf N-Strike Modulus Regulator

The Nerf N-Strike Modulus Regulator is a blaster that can function as both a semi-automatic and a fully-automatic Nerf blaster, making it unique.

The Regulator has a select-fire feature allows for semi-automatic and fully-automatic firing modes and three-round bursts, making it a distinct and notable blaster.

Another advantage of the Regulator compared to other blasters on this list is its wide range of customization options, aligning with the Modulus series’ focus on customization.

The Regulator includes a storage stock, two barrel scopes, two 12-dart clips, and 24 Modulus Elite darts.
