How to Polish an AR Trigger: A Comprehensive Guide
Polishing an AR trigger is a task that requires precision and attention to detail. Whether you’re looking to improve the feel of your firearm or enhance its aesthetics, this guide will walk you through the process step by step.
Understanding the AR Trigger
The AR trigger is a critical component of your firearm, directly affecting its accuracy and reliability. It consists of several parts, including the trigger bow, trigger bar, sear, and hammer. Before you begin polishing, it’s essential to understand these components and how they work together.
| Component | Description |
|---|---|
| Trigger Bow | The main part of the trigger that you pull to fire the gun. |
| Trigger Bar | Connects the trigger bow to the sear, transferring the pull to the hammer. |
| Sear | Engages with the hammer, holding it in place until the trigger is pulled. |
| Hammer | Strikes the firing pin, causing the bullet to be fired. |
Gathering Your Materials
Before you start polishing, gather all the necessary materials. You’ll need a polishing compound specifically designed for metal, a polishing cloth or pad, a trigger pull gauge, and a clean, well-lit workspace.
- Polishing Compound: Look for a compound that is safe for use on firearms and designed for metal polishing.
- Polishing Cloth or Pad: A microfiber cloth or a polishing pad will work well for this task.
- Trigger Pull Gauge: This tool will help you measure the trigger pull weight after polishing.
- Clean Workspace: Ensure your workspace is clean and well-lit to avoid any accidents or mistakes.
Preparation
Before you begin polishing, it’s crucial to prepare your AR trigger. Here’s what you need to do:
- Disassemble the firearm: Remove the magazine, cylinder, and any other components to access the trigger assembly.
- Remove the trigger: Carefully remove the trigger from the firearm, ensuring you don’t lose any small parts.
- Clean the trigger: Use a cleaning solvent and a brush to remove any dirt, grime, or old lubricant from the trigger and its components.
The Polishing Process
Now that your trigger is clean and ready, it’s time to start polishing. Follow these steps:
- Apply the polishing compound: Use a small amount of the polishing compound on your polishing cloth or pad.
- Polish the trigger: Gently rub the compound onto the trigger, focusing on any areas with visible wear or blemishes.
- Use a circular motion: Apply even pressure while using a circular motion to ensure an even finish.
- Check your progress: Periodically check the trigger’s surface to ensure you’re achieving the desired result.
Finishing Touches
Once you’ve polished the trigger to your satisfaction, it’s time to apply a protective coating. Here’s how to do it:
- Choose a lubricant: Select a high-quality lubricant designed for firearms, such as a dry film lubricant or a traditional oil.
- Apply the lubricant: Use a clean cloth to apply a thin layer of lubricant to the trigger and its components.
- Wipe away excess: Use a clean, dry cloth to wipe away any excess lubricant.
Reassembly and Testing
After your trigger has been polished and lubricated, it’s time to reassemble the firearm and test the trigger pull:
- Reassemble the firearm: Carefully put all the components back together, ensuring that everything is in the correct position.
- Test the trigger pull: Use the trigger pull gauge to measure the weight of the pull. It should be within the manufacturer’s specifications.
- Adjust if necessary: If the trigger pull is not within
