Ar 15 Trigger Job Polish: A Comprehensive Guide
Polishing the trigger on your AR-15 is a task that can significantly enhance the overall shooting experience. It’s not just about making the gun feel better; it’s about improving its performance. In this detailed guide, we’ll delve into the process, the tools you’ll need, and the potential benefits of a polished trigger job.
Understanding the Trigger Mechanism
The trigger mechanism is a critical component of any firearm. It’s the part that initiates the firing sequence. In an AR-15, the trigger mechanism is a complex assembly that includes the trigger, sear, hammer, and various springs. When you pull the trigger, these components work together to release the hammer, which in turn strikes the primer of the cartridge, causing the gun to fire.
Over time, the trigger can become gritty, heavy, or inconsistent. This can be due to wear, dirt, or poor maintenance. A polished trigger job can help restore the smoothness and consistency of the trigger pull.
Tools and Materials Needed
Before you start, gather the following tools and materials:
| Tool/Item | Description |
|---|---|
| Trigger Pull Gauge | Used to measure the weight of the trigger pull before and after the job. |
| Trigger Job Kit | Contains the necessary files, hones, and polishing compounds for the job. |
| Microfiber Cloths | Used for cleaning and applying polishing compounds. |
| Compressed Air | For blowing out dust and debris from the trigger assembly. |
| Trigger Pull Spring | Optional, for adjusting the trigger pull weight. |
The Process
Here’s a step-by-step guide to performing a trigger job on your AR-15:
-
Disassemble the firearm according to the manufacturer’s instructions. This typically involves removing the magazine, bolt carrier group, and the upper receiver.
-
Remove the trigger assembly from the upper receiver. This usually requires the use of a trigger puller.
-
Clean the trigger assembly thoroughly. Use a solvent to remove any grease, oil, or dirt. Then, use compressed air to blow out any remaining debris.
-
Measure the trigger pull weight using a trigger pull gauge. This will give you a baseline to compare against after the job.
-
Using the files and hones provided in your trigger job kit, carefully file and hone the surfaces of the trigger, sear, and hammer. The goal is to remove any burrs or high spots and create a smooth, consistent surface.
-
Apply a polishing compound to a microfiber cloth and gently rub it onto the trigger surfaces. This will help to further smooth out the surfaces and improve the feel of the trigger pull.
-
Reassemble the trigger assembly and reinstall it into the upper receiver.
-
Test the trigger pull weight again using the trigger pull gauge. It should be lighter and smoother than before.
Benefits of a Polished Trigger Job
There are several benefits to performing a polished trigger job on your AR-15:
-
Improved Trigger Pull Weight: A polished trigger job can reduce the weight of the trigger pull, making the gun easier to shoot accurately.
-
Increased Consistency: A polished trigger will provide a more consistent pull, which is crucial for accuracy.
-
Enhanced Feel: A smoother trigger pull can make the shooting experience more enjoyable.
-
Increased Safety: A well-maintained trigger mechanism is less likely to fail, which can help prevent accidents.
While a polished trigger job can be a rewarding DIY project, it’s important to note that it requires patience, attention to detail, and a certain level of skill. If you’re not confident in
