### Understanding the AR-15 Accu-Wedge
**What is an Accu-Wedge?**
An Accu-Wedge is a small, typically polymer or rubber buffer designed to fit snugly between the upper and lower receivers of an AR-15. Its primary function is to eliminate or minimize any unwanted movement or “slop” between these two critical components. This movement, even if seemingly insignificant, can negatively impact accuracy, especially at longer ranges.
**The Science Behind Receiver Play**
AR-15 receivers are manufactured to specific tolerances, but slight variations are inevitable. Over time, wear and tear can also contribute to increased play. This play can cause inconsistencies in barrel alignment and sight picture, leading to decreased precision. The Accu-Wedge acts as a shim, filling the gap and providing a more stable platform.
**Different Types of Accu-Wedges**
While the basic principle remains the same, Accu-Wedges are available in various shapes, sizes, and materials. Some are designed for specific AR-15 models, while others are more universal. Materials range from softer rubber compounds to more rigid polymers. Softer wedges may compress more easily, while firmer wedges offer greater stability but may require more force to install.
**Why is Receiver Tightness Important?**
* **Improved Accuracy:** A tighter receiver fit translates directly to more consistent shot placement. By minimizing movement between the upper and lower receivers, the Accu-Wedge helps maintain a stable platform for accurate shooting.
* **Enhanced Reliability:** Excessive play can also contribute to accelerated wear on other components. A properly installed Accu-Wedge can help reduce stress on critical parts, potentially extending the lifespan of your AR-15.
* **Better Shooting Experience:** A wobbly or loose AR-15 can be distracting and uncomfortable to shoot. Eliminating receiver play improves the overall shooting experience, making it more enjoyable and less fatiguing.
**The Evolution of the Accu-Wedge**
Originally, shimming or custom fitting was the only way to address AR-15 receiver play. The Accu-Wedge emerged as a simpler, more accessible solution for shooters of all levels. It provided a drop-in fix that didn’t require specialized gunsmithing skills.
### Selecting the Right Accu-Wedge for Your AR-15
Choosing the correct Accu-Wedge is crucial for optimal performance. Here’s what to consider:
* **Material:** Consider the trade-offs between softer rubber and harder polymer wedges. Rubber wedges are generally easier to install and provide some shock absorption, while polymer wedges offer greater rigidity and resistance to wear.
* **Size and Shape:** Ensure the Accu-Wedge is appropriately sized for your AR-15. Some wedges are designed for specific receiver types (e.g., mil-spec vs. commercial). Check product descriptions carefully.
* **Brand Reputation:** Opt for reputable brands known for producing high-quality AR-15 accessories. Research customer reviews and seek recommendations from experienced shooters.
* **Adjustability:** Some Accu-Wedges are adjustable, allowing you to fine-tune the fit and tension. This can be particularly useful if your AR-15 has significant receiver play.
**Things to Avoid:**
* **Generic or Unbranded Wedges:** These may be made from inferior materials and may not fit properly.
* **Overly Thick Wedges:** Forcing an overly thick wedge can damage your receivers.
### Step-by-Step Guide: How to Adjust an Accu-Wedge AR15
Now, let’s get to the practical part: installing and adjusting your Accu-Wedge. Follow these steps carefully for optimal results:
1. **Ensure Your AR-15 is Unloaded and Safe:** This is the most important step. Double-check that the rifle is completely unloaded and that the chamber is empty.
2. **Separate the Upper and Lower Receivers:** Push out the rear takedown pin and separate the upper and lower receivers.
3. **Locate the Accu-Wedge Installation Point:** The Accu-Wedge is typically installed in the rear of the lower receiver, directly behind the takedown pin lug.
4. **Insert the Accu-Wedge:** Place the Accu-Wedge into the designated space. You may need to use slight pressure to seat it properly. Some wedges may require trimming for a perfect fit.
5. **Reassemble the Receivers:** Carefully align the upper and lower receivers and push the rear takedown pin back into place. It may require slightly more force than usual due to the added tension from the Accu-Wedge.
6. **Test the Fit:** Check for receiver play. The receivers should fit snugly together with minimal to no movement. If there is still play, you may need to adjust or replace the Accu-Wedge.
7. **Adjusting the Accu-Wedge (If Adjustable):** If your Accu-Wedge is adjustable, follow the manufacturer’s instructions to fine-tune the tension. Typically, this involves tightening or loosening a screw or nut on the wedge.
8. **Function Test:** After installation, perform a function test to ensure that all components are operating correctly. Check the trigger pull, safety selector, and magazine release.
**Common Installation Problems and Solutions:**
* **Wedge Too Thick:** If the receivers are difficult to reassemble, the wedge may be too thick. Try trimming a small amount of material from the wedge.
* **Wedge Too Loose:** If there is still significant play after installation, the wedge may be too thin. Try using a thicker wedge or shimming the existing wedge.
* **Wedge Won’t Stay in Place:** Some wedges may have a tendency to fall out during disassembly. Use a small amount of adhesive to secure the wedge in place.
### Maintaining Your Accu-Wedge for Long-Term Performance
Proper maintenance is essential for ensuring the longevity and effectiveness of your Accu-Wedge:
* **Regular Inspection:** Periodically inspect the Accu-Wedge for wear and tear. Replace it if you notice any cracks, deformation, or significant wear.
* **Cleaning:** Clean the Accu-Wedge with a mild solvent and a soft cloth to remove any dirt or debris.
* **Lubrication:** Apply a small amount of lubricant to the Accu-Wedge to prevent it from drying out and cracking.
