Are you looking to upgrade your firearm's trigger system? Whether you have an AK or AR-15 platform, or even some handguns, there are a few options for you to choose from. You may have heard about binary triggers but aren't quite sure what they are or how they work, which is why we are here. Our team at Core Vision Training is going to break down everything you need to know about binary triggers, from understanding their concept and design to how they operate and the legal regulations surrounding them, we've got you covered.

Understanding a Binary trigger

You have things like optics and suppressors, as well as foregrips and pistol braces to customize your firearms, but then you have the trigger upgrades like binary triggers.

No, binary triggers do not make your guns fully-automatic, nor do they fire in burst mode. However, binary triggers offer a unique firing mode, enabling semi-automatic and binary fire. They enhance the shooter's rate of fire without modifications, allowing fast double taps through a second sear. Binary triggers can be placed into a variety of different firearms, from 5.56 rifles to small caliber pistols. Federal law currently permits binary triggers, but state regulations may vary. Popular for competition use, they provide faster split times.

Concept and Design of a Binary Trigger

The concept and design of a binary trigger involve enhancing the firing capability of a firearm. It is a single function trigger that fires a round upon trigger pull and a second round upon trigger release, which is close to burst fire. This mechanism utilizes a disconnector, selector, and second sear to mimic the firing of a fully automatic or burst fire weapon. Importantly, binary triggers are legal modifications as long as they comply with federal regulations.

How Binary Triggers Operate

Binary triggers operate by harnessing the energy of the firearm's firing pin and cartridge primer. When the trigger is pulled, the firing pin strikes the primer, initiating the firing of the round. Upon trigger release, the disconnector re-engages the sear, allowing the hammer to strike the firing pin again, firing a second round. The binary mode is activated by the safety selector, differentiating it from a standard trigger.

The Mechanism and Functioning Explained

The binary trigger operates as a semi-automatic trigger with a binary mode, allowing for a round to be fired upon trigger pull and trigger release. This modification involves the trigger, disconnector, and selector of the firearm, enabling a rapid double shot firing experience. The disconnector plays a crucial role in ensuring safe and intended operation. When engaged, the shooter can fire a round on the first shot and a second shot when releasing the trigger.

Are Binary Triggers Legal Across the United States?

Understanding the legal status of binary triggers is crucial. While they are legal at the federal level, individual states may have their own regulations. It's important for gun owners to be aware of their state laws and seek legal advice to ensure compliance. The ATF oversees the legality of binary triggers in the United States.

Legal Regulations in Various States

Binary triggers are legal in states like New York, Rhode Island, and Florida, with certain restrictions. However, states such as California, Maryland, and New Jersey have stricter regulations. These states are also strict with other attachments and modifications, such as suppressors. It's important for gun owners to stay updated on the latest legal requirements as the legality of binary triggers can change. Consulting state and federal laws, as well as legal professionals, is vital for accurate and up-to-date information.

Legal Consequences of Non-Compliance

Non-compliance with federal and state regulations regarding binary triggers can have serious legal repercussions. Using or possessing binary triggers in states where they are prohibited can result in criminal charges.

For example, if you are a convicted felon, you shouldn’t have a gun to begin with, nor are you allowed to have these triggers, and you can’t even have body armor. Gun owners who fail to comply with regulations like this may face fines, confiscation of firearms, and loss of their firearm rights. To avoid legal issues, it is essential for gun owners to understand and abide by the legal requirements surrounding binary triggers.

Why would You Consider a Binary Trigger?

While they serve no practical purpose, many individuals enjoy installing them to plink on the range with friends.
