Are you intrigued by the AR-15 rifle and its various modifications? One of the most crucial components of this iconic firearm is the sear. In this article, we will delve into the details of the AR-15 sear, exploring its function, importance, and how it affects the overall performance of the rifle. Get ready to uncover the secrets behind this vital part of the AR-15.
Understanding the AR-15 Sear
The AR-15 sear is a critical component responsible for the firing mechanism of the rifle. It is a small, often overlooked part that plays a significant role in the operation of the firearm. The sear is a spring-loaded lever that holds the hammer in place until the trigger is pulled. When the trigger is activated, the sear releases the hammer, allowing it to strike the firing pin and ignite the primer, thus firing the rifle.
Function and Importance
The AR-15 sear is designed to ensure that the rifle fires only when the trigger is pulled. This is crucial for safety reasons, as it prevents the rifle from firing unintentionally. The sear also helps in controlling the rate of fire, as it can be adjusted to allow for semi-automatic or fully automatic firing modes, depending on the rifle’s configuration.
Here’s a table summarizing the key functions and importance of the AR-15 sear:
| Function | Importance |
|---|---|
| Prevents unintentional firing | Ensures safety |
| Controls rate of fire | Enables semi-automatic or fully automatic firing |
| Ensures proper functioning of the rifle | Keeps the rifle reliable and accurate |
Types of AR-15 Sear
There are several types of AR-15 sears available, each with its own unique features and benefits. Some of the most common types include:
- Standard Sear: This is the most common type of sear and is suitable for most rifles. It provides a good balance between safety and functionality.
- Lightened Sear: This type of sear is designed for those who prefer a lighter trigger pull. It can improve the overall shooting experience but may require additional adjustments to maintain safety.
- Heavy Sear: A heavy sear is ideal for those who want to ensure maximum safety. It provides a heavier trigger pull, making it less likely for the rifle to fire unintentionally.
- Custom Sear: Custom sears are designed for specific applications and can offer unique features, such as adjustable trigger pull or improved safety mechanisms.
Installing and Maintaining the AR-15 Sear

- Disassemble the rifle and remove the bolt carrier group.
- Remove the existing sear and spring from the upper receiver.
