Finding the right parts to restore or replace your original AR-15 handguard can be tricky. This guide details the components you'll need, clarifying the differences between various styles and offering tips for successful installation. We'll focus on the classic, non-free-float handguards common on early AR-15 rifles.
Understanding Original AR-15 Handguards
Before diving into specific parts, it's crucial to understand that "original" can be subjective. The design evolved over time. However, we'll focus on the common features of the early, non-free-float handguards typically associated with the term "original." These handguards usually attach directly to the barrel nut and use a delta ring to secure them in place.
Key Components of an Original AR-15 Handguard
This section breaks down the essential parts needed for a complete original AR-15 handguard assembly:
1. Handguard Tube(s):
- Description: These are the main cylindrical components that surround the barrel. Original handguards often consist of two halves that clamp around the barrel.
- Variations: Lengths and diameters can vary slightly depending on the manufacturer and era of the rifle.
- Material: Typically made of aluminum or polymer.
2. Delta Ring:
- Description: A metal ring that fits around the barrel nut and helps secure the handguard in place. It's crucial for a tight and stable fit.
- Variations: While generally standardized, minor variations might exist across manufacturers.
- Material: Usually steel.
3. Delta Ring Retaining Pin:
- Description: A small pin that fits through the delta ring and holds it securely against the barrel nut. This pin prevents the handguard from shifting or loosening during firing.
- Material: Steel.
4. Handguard Cap(s):
- Description: These end caps are usually found on the front end of the handguard tube(s), providing a clean and finished look. They can also help prevent debris from entering the handguard.
- Variations: Shape and design can vary, but their function remains consistent.
- Material: Usually metal or plastic.
Troubleshooting Common Issues
During reassembly or replacement, you might encounter some common problems:
- Handguard Doesn't Fit: Double-check you have the correct handguard for your barrel nut and ensure the delta ring is properly seated.
- Handguard is Loose: The delta ring might be damaged or incorrectly positioned. Verify the retaining pin is correctly installed and the delta ring is snug against the barrel nut.
- Missing Parts: If you are missing any of these components, you may need to source replacements from reputable suppliers specializing in AR-15 parts.
Sourcing Replacement Parts
Finding replacement parts for original AR-15 handguards can be done through various avenues:
- Gunsmiths: A local gunsmith can often source the parts you need or point you in the right direction.
- Online Retailers: Many online retailers specialize in AR-15 parts and accessories. However, carefully verify the seller’s reputation before purchasing.
- Specialty Gun Stores: Check with your local gun stores; they may carry these parts or be able to order them for you.
By carefully identifying the specific components needed and sourcing them from reputable sources, you can successfully restore or replace your original AR-15 handguard. Remember to always prioritize safety when working with firearms and their components.
