The AR-15 platform, a staple in the world of modern sporting rifles, is celebrated for its modularity and adaptability. One of the many components that contribute to this versatility is the forward assist. But what is it, and why is it important? This guide will delve into the world of the forward assist, explaining its purpose, detailing the necessary steps for a successful installation, and providing helpful troubleshooting tips. By following these instructions, you’ll learn how to properly install a forward assist on your AR-15 or compatible firearm, ensuring optimal functionality and safety.
The forward assist is a small, but important, component located on the upper receiver of your AR-15. Its primary function is to ensure that the bolt carrier group is fully seated and locked into battery. Sometimes, particularly after a manual operation or when encountering a stubborn cartridge, the bolt might not close completely. The forward assist provides a mechanical means of manually pushing the bolt carrier group forward, ensuring a secure lockup. This is crucial for reliable cycling and consistent accuracy. Failure to properly lock the bolt can lead to malfunctions or, in some cases, misfires.
Safety Precautions
Before you begin the installation process, prioritize safety. Handling firearms responsibly is paramount. This process involves working with tools and small components, so attention to detail is essential.
First, *clear the firearm*. Remove the magazine and visually and physically inspect the chamber to verify it is empty. Never assume a firearm is unloaded; always confirm it. Then, *wear safety glasses*. These will protect your eyes from any stray pieces or debris during the installation. *Work in a well-lit, uncluttered space*. A clean and organized workspace will help you keep track of the small parts and prevent accidental damage. *Warning:* This guide is intended for informational purposes only. Always exercise caution and follow all safety guidelines. Any modifications made to a firearm are done at your own risk.

Tools and Materials Needed
Let’s talk about the tools and materials you will need to properly install a forward assist. You’ll need a forward assist assembly, which typically includes the following:
- The forward assist itself: This is the main body of the component that you will attach to the upper receiver.
- The forward assist spring: This provides the return force for the forward assist, ensuring it returns to its normal position after being depressed.
- The forward assist plunger: This part moves with the return spring and helps push the bolt carrier group forward.
- The forward assist pin: This small roll pin will secure the housing to the upper receiver.
You’ll also need the following tools:
- A set of roll pin punches: It’s best to have a set, as you want to choose the punch that best fits the forward assist pin. Ensure that your punches have the correct size to avoid damaging the pin or the upper receiver.
- A hammer: Appropriate for use with your roll pin punches.
- A vice: A vice can be very useful in the installation process, but it’s optional.
- Gunsmithing hammer (if using a vice): This is a small hammer to gently tap the forward assist pin into place if you’re using a vice.
- Bench block (optional): A bench block provides a stable surface for working on the firearm.
- Small file or deburring tool (optional): Sometimes, the forward assist hole might require some minor deburring.
- Gun oil or lubricant: This will help make installation easier.
Preparation
Before you begin, some preparation steps are essential.
Identify the exact location where the forward assist housing will be positioned. Examine the upper receiver. This is the area on the upper receiver where the forward assist will be installed.
Inspect the upper receiver, paying close attention to the hole for the forward assist pin. Ensure the hole is clear of any obstructions or burrs. If you see any rough edges or debris, use a small file or deburring tool to gently clean the hole.
Optional: Apply a thin coating of lubricant to the forward assist housing and pin. This can help with installation and reduce friction.
The Installation Process
Now, let’s get to the actual installation of the forward assist. Follow these steps carefully:
Install the Spring and Plunger
First, install the spring and plunger. Insert the forward assist spring into the housing. Compress the spring and insert the plunger. You might need a small tool to help compress the spring during this step.
Aligning the Forward Assist Housing
Next, align the forward assist housing. Place the upper receiver securely in your workspace, giving you clear access to the area where the forward assist will be installed. Align the forward assist housing with the corresponding hole on the upper receiver. Ensure the housing is straight and flush against the upper receiver.
Installing the Roll Pin
The critical part: Install the roll pin. Position the forward assist in place on the upper receiver. Select the roll pin punch of the correct size for your forward assist pin. Carefully place the punch on the roll pin and begin tapping with the hammer. It is critical that the roll pin is driven in straight. Use controlled, gentle taps. Make sure the pin is flush with the upper receiver. If you are using a vice, this step may be easier. You can hold the upper receiver in the vice and use a gunsmithing hammer to drive the pin in.
Check Your Work
Check your work. Once the pin is in place, use your fingers or a small tool to confirm it is properly seated. The pin should be flush with the surface of the upper receiver. If you can push the pin through to the other side, you need to re-insert the pin and try again.
Testing
Testing is essential: After completing the installation, test the forward assist to ensure everything functions correctly. Press the forward assist and verify that it moves smoothly and returns to its original position without any sticking or resistance. Ensure that the forward assist does not obstruct the bolt carrier group during operation. Cycle the action and make sure the bolt locks up properly. You should hear a distinct “click” or feel a solid lockup. If the bolt does not lock up, there may be an obstruction or an issue with the alignment.
Troubleshooting
Sometimes, even with the best efforts, problems can arise. Here are some common troubleshooting scenarios:
Forward Assist Won’t Depress
The forward assist won’t depress. This can be caused by a number of factors. Check that the pin is properly aligned and seated. Ensure the spring and plunger are correctly installed and not obstructed. There may be some interference from a burr or debris. Make sure the housing is aligned correctly and flush with the upper receiver.
Forward Assist is Loose
The forward assist is loose. If the forward assist is loose, the roll pin may not be fully seated, or you may have used the wrong size roll pin. If this is the case, you will need to remove the pin and start over.
Bolt Won’t Lock
The bolt won’t lock. Double-check the alignment of the forward assist and the internal components. There might be an obstruction or issue with the bolt carrier group. Examine the bolt carrier group for damage, and consider disassembling and reassembling it to ensure proper function.
Conclusion
The forward assist is often a forgotten component, but it plays an important role in ensuring the proper and reliable functioning of your AR-15. By following these simple steps, you can learn how to successfully install a forward assist. Always prioritize safety, and remember to exercise caution when handling firearms.
In conclusion, installing a forward assist is a straightforward process that can significantly enhance the reliability of your AR-15. Once you’ve become familiar with the steps and materials, you can be certain that you can successfully perform the procedure.
Remember to double-check your work and always prioritize safety.
