Introduction
The AR-15. It’s an icon, a testament to modularity and customization, and a favorite of firearm enthusiasts worldwide. From its humble beginnings to its current widespread popularity, the AR-15 has consistently proven its adaptability. A cornerstone of its design is its versatility; a rifle that can be tailored to suit individual preferences and shooting needs. One of the most significant avenues for this personalization lies in the handguard. And when considering upgrades, the decision often leads to a crucial question: How do you integrate a high-performance free float handguard while retaining the familiar A2 front sight? This article delves into just that, exploring the world of free float handguards specifically designed to work seamlessly with the classic A2 front sight, and providing a comprehensive guide for those seeking to enhance their rifle’s capabilities.
The standard AR-15 platform, as it comes from the factory, offers a basic handguard, typically made of polymer. While functional, these handguards often contact the barrel, creating stress and hindering the rifle’s full potential for accuracy. The solution? Free float handguards.
Free float handguards, as the name suggests, allow the barrel to “float” freely within the handguard, without any point of contact. This decoupling is critical. By eliminating any pressure applied to the barrel by the handguard or accessories attached to it, the barrel can vibrate and move naturally with each shot. The result is often a dramatic improvement in accuracy. The elimination of this contact also improves barrel cooling, as air can circulate more freely. But achieving this freedom isn’t always straightforward, especially when your rifle is equipped with the time-tested A2 front sight.
The A2 front sight assembly is a familiar sight to many AR-15 owners. This fixed sight post is typically integrated into the gas block, providing a robust and reliable front sight. Its fixed nature, however, presents a challenge when upgrading to a free float handguard. The handguard needs to accommodate the A2 sight’s presence, which often requires specific design considerations. It’s not just about swapping one part for another; it’s about ensuring compatibility and maintaining the rifle’s functionality. The goal is to modernize and improve the rifle without sacrificing the advantages provided by the A2 front sight.
Why hold onto the A2 sight? There are several compelling reasons. For many shooters, the A2 front sight is a familiar and reliable sight picture. It’s cost-effective – replacing a perfectly functional A2 sight just to accommodate a different handguard adds unnecessary expense. And for those prioritizing simplicity and speed of deployment, the A2 sight’s straightforward design offers immediate usability without requiring batteries or adjustments.
So, if you want the benefits of a free float handguard without replacing your A2 front sight, what are your options?
Exploring the Different Options
Let’s explore the main types of free float handguards that cater to the AR-15 with an A2 front sight. The choices can be broadly categorized by how they integrate with the A2 front sight.
Drop-In Free Float Handguards
One popular choice is the drop-in free float handguard. These are designed to replace the standard handguards without requiring any permanent modifications to the rifle. They typically install by simply removing the existing handguards and sliding the new one into place.
These handguards offer an accessible entry point to free float technology. Installation is often incredibly simple, making it a great option for those who prefer to avoid any complex gunsmithing. You typically won’t need to remove or modify the A2 front sight, which is a significant advantage. Many come with built-in or easily attachable accessory rails, which can enhance your rifle’s versatility.
However, drop-in designs sometimes present limitations. Compared to handguards that offer more robust free float capabilities, drop-in handguards might not always be as rigidly mounted. The overall rigidity can be a key element in achieving optimal accuracy. While these handguards can significantly improve accuracy compared to non-free float options, they might not provide the absolute performance gains of more complex setups. You may also find that the accessory mounting options are more limited compared to other types.
Consider these products as possible options. Brands such as Midwest Industries, Magpul, and UTG frequently offer drop-in free float handguards, often with features like M-LOK or Picatinny rails for accessory mounting. The availability of options and price points makes this a practical choice for many shooters.
Free Float Handguards Designed to Accommodate the A2 Front Sight
Another path involves free float handguards specifically designed to accommodate the A2 front sight. These handguards present a more involved installation process, but they provide a truly free-floating barrel and often offer the greatest potential for performance enhancement.
These handguards are specifically engineered with a cutout, a gap, or an extension that allows the handguard to encompass the barrel without touching the A2 front sight. These handguards are often more robust and are designed to eliminate all contact with the barrel.
The benefits are significant. These handguards provide the best in terms of accuracy, rigidity, and mounting options. You’ll typically have a wide range of accessory attachment possibilities. You’ll be able to tailor your rifle to your exact needs and shooting style.
The installation process usually involves removing the existing handguards and the delta ring assembly (which secures the handguards to the barrel nut). You’ll then install a barrel nut (often proprietary to the handguard manufacturer). This nut serves as the foundation for attaching the new handguard. Once the barrel nut is in place, the free float handguard is installed over the barrel, accommodating the A2 front sight. The handguard is then secured to the barrel nut.
Expect to invest more time and effort in the installation process. But for serious shooters looking to maximize their AR-15’s potential, the advantages are well worth the effort. Examples of quality manufacturers that offer these types of handguards include Aero Precision, Geissele, and Midwest Industries, each producing handguards that are well-regarded in the industry.
Other Important Points
Finally, keep other important points in mind. Handguard length is a key consideration. Handguards are available in various lengths, ranging from carbine to rifle-length, and your choice should complement your gas system, personal preferences and aesthetic goals. Make sure to find the right balance between length and functionality for your specific application.
Various mounting options are available. Picatinny rails, M-LOK, and KeyMod are popular choices. They allow you to attach accessories like lights, lasers, vertical grips, and other equipment. Each system has its own strengths and weaknesses, so selecting the correct one that works with your accessories is a must.
Handguard materials impact both weight and durability. Aluminum is a common and reliable material, known for its balance of strength and weight. Carbon fiber offers a lighter alternative but comes with a higher price point. Carefully consider how materials affect your rifle’s overall performance, feel, and usability.
The Installation Process: A General Overview
Before diving into any modifications on your firearm, safety must be your paramount concern. Always treat every firearm as if it is loaded. Verify that your AR-15 is unloaded. Remove the magazine, visually inspect the chamber to confirm that it’s empty. If possible, work in a well-lit and ventilated area, and always follow the manufacturer’s safety instructions.
You’ll need a few key tools to install a free float handguard for an A2 front sight. These might include an armorers wrench or other compatible wrench for removing or tightening the barrel nut. A set of punches to help disassemble the old handguard components. A vise block to secure your upper receiver will greatly assist in the process, and you’ll also need the necessary wrenches, screwdrivers, and other hand tools.
Installation Instructions Vary
Installation varies depending on the handguard type.
To install a drop-in free float handguard: Remove the old handguards. Remove the delta ring assembly and handguard cap (if applicable). Slide the new handguard into place. Tighten securely. The process is usually straightforward, requiring only basic hand tools.
