A drop-in auto sear is a conversion device that allows a semiautomatic AR-15 to fire full-auto. The device is a small metal part that replaces the sear, which is the part of the trigger group that holds the hammer back until the trigger is pulled. While the auto sear requires some modification to the AR-15, it is a relatively simple and inexpensive way to convert the rifle to full-auto.
What is an Automatic Sear?
An automatic sear is a device that, when installed in a firearm, allows the firearm to fire in fully automatic or burst mode. Automatic sears are generally prohibited under United States federal law, with a few rare exceptions.
An automatic sear is usually a small, metal device that is installed in the fire control group of a firearm. When the firearm is in semi-automatic mode, the sear holds the hammer or striker in the cocked position. When the firearm is switched to fully automatic mode, the sear releases the hammer or striker, allowing the firearm to fire continuously.
Automatic sears are generally prohibited under United States federal law. The National Firearms Act of 1934 placed strict regulations on the manufacture, sale, and possession of automatic firearms. The Firearm Owners Protection Act of 1986 further restricted the manufacture and sale of automatic sears, and made it illegal to possess an automatic sear without the proper paperwork.
There are a few limited exceptions to the ban on automatic sears. The Bureau of Alcohol, Tobacco, Firearms and Explosives has approved the manufacture and sale of automatic sears for use in machine guns that are registered with the federal government. Automatic sears may also be possessed by museums and other entities that are exempt from the National Firearms Act.
Types of Auto Searing Systems
There are two main types of auto searing systems: those that use a mechanical device to sear the meat, and those that use a heated plate to sear the meat.
Mechanical auto searing systems typically use a rotating blade or disk to sear the meat. The meat is placed on a rotating platform, and the blade or disk sears the meat as it rotates. These systems are often used in commercial kitchens, as they can sear a large amount of meat at once.
Heated plate auto searing systems use a heated plate to sear the meat. The meat is placed on the heated plate, and the heat sears the meat. These systems are often used in home kitchens, as they are less expensive than mechanical searing systems.
How to Install a Drop In Auto Sear
Before you can install a drop in auto sear, you need to purchase one. You can find drop in auto sears for sale online or at some gun stores. Once you have your drop in auto sear, follow these steps to install it:
- Make sure your AR-15 is unloaded and the safety is on.
- Remove the upper receiver from the lower receiver.
- Take out the bolt carrier group and charging handle.
- Look inside the receiver and locate the sear pin. This is the small pin that holds the factory sear in place.
- Use a punch or other small tool to drive the sear pin out.
- Insert the drop in auto sear into the receiver.
- Use the punch to drive the sear pin back in place.
- Reassemble the AR-15.
Your drop in auto sear is now installed and ready to use.
Parts you will need (and what they do)
When you insert the auto sear into the trigger mechanism, it holds the trigger in the sear position. This allows the gun to fire continuously. The auto sear can be made from a variety of materials, but the most common is steel. You can purchase an auto sear that is already made, or you can make your own.
Safety Precautions When Using an Auto Sear
When making or using a drop in auto sear, there are a few safety precautions to keep in mind. First, always keep the auto sear in its proper place in the firearm. Second, never allow the auto sear to come in contact with any other part of the firearm. Third, make sure the auto sear is always clean and free of debris. Fourth, make sure the auto sear is properly lubricated. Fifth, always keep the auto sear away from children and never allow them to handle it.
Drawbacks of an Auto Sear System
Drop-in auto sears are a type of conversion kit that can be used to convert a semi-automatic rifle into a fully automatic rifle. While these kits are legal to purchase and own in many countries, there are some drawbacks to using them.
- One of the biggest drawbacks is that they are very difficult to install. Most kits require that you drill and tap new holes in your receiver, which can be difficult and time-consuming. Additionally, if not installed correctly, drop-in auto sears can be extremely dangerous.
- Another drawback is that they significantly increase the wear and tear on your rifle. Full-auto rifles fire at a much higher rate than semi-automatic rifles and can quickly wear out parts like the bolt carrier group and barrel.
- Finally, drop-in auto sears are expensive. Kits can cost anywhere from $500 to over $1000, which is a significant investment.
