Ruger AR 556 Handguard Install: A Comprehensive Guide

Installing a handguard on your Ruger AR 556 is a great way to enhance its aesthetics and functionality. Whether you’re looking to improve your grip, add a Picatinny rail, or simply customize your rifle, a handguard can make a significant difference. In this guide, we’ll walk you through the process of installing a handguard on your Ruger AR 556, step by step.

Choosing the Right Handguard

Before you begin the installation process, it’s important to choose the right handguard for your Ruger AR 556. There are several factors to consider, such as material, size, and compatibility with your rifle.

• Material: Handguards are available in various materials, including aluminum, polymer, and carbon fiber. Aluminum is a popular choice due to its durability and lightweight nature. Polymer is also a good option, as it’s lightweight and offers a comfortable grip. Carbon fiber is the most expensive option, but it’s also the strongest and most durable.
• Size: Ensure that the handguard you choose is the correct size for your Ruger AR 556. Most handguards are designed to fit specific rifle models, so it’s important to check the specifications before making a purchase.
• Compatibility: Verify that the handguard is compatible with your rifle’s barrel nut and gas block. Some handguards may require a specific type of barrel nut or gas block adapter.

Once you’ve selected the perfect handguard for your Ruger AR 556, it’s time to move on to the installation process.

Tools and Materials Needed

Before you start the installation, gather the following tools and materials:

• Handguard
• Hex wrench
• Barrel nut wrench
• Gas block wrench
• Locking bolt
• Locking bolt wrench
• Grease or lubricant

Ensure that all tools are in good condition and that you have the appropriate size wrenches for your handguard and barrel nut.

Installation Steps

Follow these steps to install your handguard on your Ruger AR 556:

1. Remove the Gas Block: Use the gas block wrench to remove the gas block from the barrel. This will allow you to access the barrel nut and handguard.
2. Loosen the Barrel Nut: Use the barrel nut wrench to loosen the barrel nut. It may be necessary to use a hammer and punch to remove the nut if it’s tight.
3. Remove the Barrel: Once the barrel nut is loose, carefully remove the barrel from the rifle. Set the barrel aside for now.
4. Install the Handguard: Place the handguard over the barrel nut and ensure that it’s properly aligned with the gas block. Slide the handguard onto the barrel nut until it’s seated properly.
5. Secure the Handguard: Use the hex wrench to tighten the barrel nut onto the handguard. Be sure to apply even pressure to avoid damaging the threads.
6. Install the Gas Block: Reinstall the gas block onto the barrel, ensuring that it’s properly seated in the handguard. Use the gas block wrench to tighten the gas block into place.
7. Install the Locking Bolt: Place the locking bolt into the handguard and use the locking bolt wrench to tighten it. This will secure the handguard to the rifle.
8. Apply Lubricant: Apply a small amount of grease or lubricant to the threads of the barrel nut, gas block, and locking bolt. This will help prevent future issues and ensure a smooth installation.

Final Checks

After completing the installation, perform the following final checks:

• Functionality: Ensure that the rifle operates properly with the new handguard. Check for any misalignments or loose components.
• Fit: Verify that the handguard fits securely and that there are no gaps between the handguard and the rifle.
• Stability: Test the rifle’s stability while holding it
