### Why an Accu-Wedge Matters: Eliminating Receiver Play
Receiver play, or wobble, occurs when the upper and lower receivers of an AR-15 are not tightly fitted. This looseness can be caused by manufacturing tolerances, wear and tear, or simply the inherent design of the AR-15 platform. Even a slight amount of play can affect accuracy, especially at longer ranges. An Accu-Wedge is a simple, inexpensive polymer buffer that fills the gap between the receivers, creating a snug fit and eliminating unwanted movement. It’s a crucial component for any serious AR-15 enthusiast seeking to maximize accuracy and reliability.
### What is an Accu-Wedge? Deep Dive into the Component
An Accu-Wedge is a small, wedge-shaped piece of polymer (typically rubber or polyurethane) designed to be inserted into the lower receiver of an AR-15, behind the takedown pin lug. Its primary function is to provide upward pressure on the upper receiver, effectively tightening the fit between the two receivers. This eliminates wobble and reduces vibration, leading to improved accuracy and consistency. The beauty of the Accu-Wedge lies in its simplicity and ease of installation. It requires no permanent modifications to the firearm, making it a reversible and non-destructive upgrade.
Accu-Wedges are available in various sizes and shapes to accommodate different AR-15 models and levels of receiver play. Some are solid, while others have a hollow core for added compression. The choice of Accu-Wedge depends on the specific rifle and the amount of play that needs to be eliminated. It’s important to select the correct size to avoid over-tightening, which can damage the receivers or cause malfunctions.
### Understanding the Principles Behind a Tight Fit
The AR-15’s design, while robust and reliable, often allows for slight variations in manufacturing. These variations, compounded by wear and tear, can result in receiver play. The Accu-Wedge works by introducing a controlled amount of tension between the receivers. This tension not only eliminates wobble but also helps to dampen vibrations caused by the firing cycle. By reducing vibration, the Accu-Wedge contributes to improved shot-to-shot consistency and overall accuracy.
The principle is similar to shimming in other mechanical systems. By adding a precisely sized shim, you can eliminate unwanted gaps and create a more stable and rigid assembly. In the case of the AR-15, the Accu-Wedge acts as that shim, ensuring a tight and secure connection between the upper and lower receivers.
### The Importance of a Properly Adjusted AR-15
A properly adjusted AR-15 is essential for optimal performance, reliability, and safety. Receiver play not only affects accuracy but can also contribute to accelerated wear and tear on critical components. A loose fit can allow dirt and debris to enter the action, leading to malfunctions and reduced lifespan. Furthermore, excessive movement between the receivers can create stress points, potentially causing damage over time.
By eliminating receiver play with an Accu-Wedge, you can ensure that your AR-15 functions as intended, providing consistent accuracy, reliable operation, and a longer service life. It’s a small investment that can yield significant returns in terms of performance and peace of mind.
