AR-15 Fully Automatic Trigger: All You Need to Know

If you're looking for a reliable and efficient fully automatic trigger for your AR-15 rifle, then you've come to the right place. In this article, we'll guide you through everything that you need to know about the AR-15 fully automatic trigger.

Understanding the AR-15 Fully Automatic Trigger

The term "fully automatic" refers to a firearm's ability to fire multiple rounds with one pull of the trigger. While semi-automatic rifles like the standard AR-15 are limited in terms of firing speed, a fully automatic variant can shoot dozens or even hundreds of rounds within minutes.

The main component that allows an AR-15 rifle to become fully automatic is its trigger mechanism. A standard gas-operated semi-automatic rifle uses a single-stage or two-stage trigger system. However, if modified correctly using compatible parts and legal methods by licensed gunsmiths or law enforcement agencies only, an existing semi-auto can be converted into full auto capability by fitting it with an appropriate full auto sear assembly unit under strict compliance of laws regulating such firearms.

Comparing Semi-Automatic vs Fully Automatic Triggers

One significant difference between these two types of triggers lies in their firing mechanisms' design and complexity. A semi-automatic trigger will have fewer moving parts than its counterpart since it must complete only one cycle per shot fired.

In contrast, a fully automatic sear assembly unit has more components necessary for handling rapid-fire rates without damage from heat buildup due continuous firing requiring precision engineering tolerances so as not cause malfunctions leading to safety hazards during usage.

An important factor in choosing which type of system is best suited for your needs depends on where and how often you plan on using your weapon—automatic triggers being more suitable when covering large areas quickly while needing high suppressive firepower against enemy forces located far away from each other like war scenarios rather than hunting.

Benefits of an AR-15 Fully Automatic Trigger

The primary advantage of the fully automatic trigger system is its rapid-fire rate. This feature is critical in situations where speed and volume are essential, such as military combat scenarios.

However, there are also some potential drawbacks to using a fully automatic trigger. For one, it can be challenging to control recoil with a high firing rate. Additionally, fully automatic rifles may not be legal for use in all applications or regions.

Tips for Choosing and Using an AR-15 Fully Automatic Trigger

If you decide that a fully automatic trigger is right for your needs based on the benefits mentioned above and other factors like gun control laws regulating firearms ownership or competition events requiring such weapons use only under strict supervision by licensed professionals:

  1. Make sure that your weapon's sear assembly unit is compatible with full-auto configuration before purchasing.
  2. Find reputable licensed gunsmiths who specialize in converting semi-automatic rifles into full auto variants.
  3. Get proper training on how to handle these types of triggers safely and effectively.
  4. Always follow local firearm regulations regarding ownership, storage, transport and usage restrictions while handling any type of firearm including those modified from their original design intent.


An AR-15 rifle equipped with a fully automatic trigger can provide significant advantages in certain situations but comes at added risks if not compliant to relevant laws regulating firearms modification. It's essential always to consider your safety first when choosing this particular system over others available out there!


What is an AR-15 fully automatic trigger?

An AR-15 fully automatic trigger is a component that when installed, allows the rifle to fire continuously as long as the trigger is held down. This type of trigger converts a semi-automatic AR-15 into a fully automatic weapon. Once activated, it will discharge rounds at an extremely fast rate with little effort from the shooter.

Many people are familiar with the term "machine gun" which describes any firearm that fires in full-auto mode or bursts. The concept behind a machine gun and an AR-15 fitted with such triggers are similar but differ in their mechanisms of operation.

The legality of owning and using such triggers varies from country to country and state laws within some countries may also vary on this issue, though generally speaking I would advise against attempting to purchase one without thoroughly researching local regulations beforehand.

Are there different types of fully automatic triggers for an AR-15?

Yes, there are several types available on the market today if you know where to look – however given how strictly regulated these components can be it's not always easy finding them legally. Some examples include Binary Triggers (which release two shots per press), Bump Stocks (a device which uses recoil action instead) or other electronic means like mechanical solenoids etc., but not all work perfectly on every weapon equally well due differences in design between each model so some experimentation may be required before settling upon one specific brand/ type over another.

Can anyone install an Ar 15 full-auto Trigger?

It's important to note that installing these kinds of components requires mechanical expertise beyond what most individuals possess – doing so without proper knowledge could result injury; even death! Additionally depending upon your location owning/ operating anything beyond semi/auto versions could land you trouble police authorities if caught making modifications dealing specifically firearms).

Some Ar 15 models allow users capable disassembling/ re-assembling various parts themselves: knowing difference between these makes/ models is key determining whether DIY installation feasible. In most cases though it's best leaving trigger upgrades professional gunsmiths who have experience with firearms on a more advanced level.

Is owning an AR-15 with full-auto trigger legal?

This question doesn't have any definitive answer since laws surrounding this can vary greatly depending upon location and context. For instance, in some US states such as Texas or Indiana residents are allowed to possess automatic weapons provided they meet certain criteria (such as proving that the firearm has been registered before 1986). However, other areas of the country may not be so lenient when it comes to such things – so always check relevant regulations first beforehand!

Additionally, note that there are international laws regarding possession/ use fully-automatic triggers; for example Canada strictly prohibits private ownership all kinds full-auto firearms without specific permission obtained beforehand from authorities).

Are there any advantages of using an Ar 15 Full-Auto Trigger over other types?

There are definitely some upsides to using a fully automatic trigger on your AR-15 if you plan on engaging large numbers targets quickly or need suppressive fire ability often used military/ law enforcement scenarios.

One major benefit having access increased firepower means less time spent reloading which could potentially save life especially during intense combat situations where speed necessary factor survival. Additionally fine-tuning settings within different types triggers allows users experiment find optimal firing rate per individual preference making sure every shot counts while minimizing ammunition waste.

However it’s important noting downsides associated with overuse this type component too: recoil generated rapid-fire will eventually cause gun wear out faster than normal usage patterns along potential jamming issues failure feed properly due excess gas build-up inside barrel/chamber area – so knowing how manage weapon appropriately crucial avoiding these risks altogether!
