Understanding the Forward Assist: A Deep Dive
The Forward Assist’s Purpose
Before we explore the benefits and drawbacks of an AR upper without forward assist, it’s crucial to grasp what the forward assist actually *is* and what it aims to accomplish. Essentially, the forward assist is a spring-loaded plunger located on the upper receiver, typically on the right side, near the charging handle. Its purpose, at its inception, was to aid in the forceful chambering of a round, especially during adverse conditions or when encountering issues like weak primer strikes or debris in the chamber.
The Historical Context
The forward assist came about during the Vietnam War, where the rifle was originally designed as the AR-15. The original AR-15 often experienced malfunctions in the harsh environment it was used. Soldiers encountered issues with the weapon due to dirt, lack of maintenance, and weak ammunition. The forward assist was intended to manually force the bolt carrier group forward and fully chamber a round that might not have gone into battery on its own. In theory, the forward assist allowed a soldier to manually push the bolt forward, overcoming slight resistance from debris or ammunition issues, and potentially keep the weapon in the fight.
The Mechanism of the Forward Assist
The mechanism itself is fairly simple. When the bolt carrier group doesn’t fully close, the forward assist can be engaged. Pushing the plunger depresses the spring, and the internal lugs on the forward assist engage the bolt carrier group, forcing it forward. This action should fully chamber the round, provided the obstruction isn’t too severe.
Variations of the Forward Assist
There are various types of forward assists, primarily differentiated by their material and design. They are typically made from steel or aluminum, and their construction can influence factors like durability and weight. Some forward assists have serrated faces to provide a better grip when depressing them. These variations often come down to the manufacturer’s preference and the overall aesthetic goals of the upper receiver design.
Advantages of an AR Upper Without Forward Assist
Weight Savings
One of the most noticeable advantages is weight savings. Removing the forward assist, which includes the plunger, spring, and associated hardware, reduces the overall weight of the upper receiver. This might seem like a minor detail, but it contributes to a slightly lighter overall rifle. This reduction in weight can improve handling characteristics, making the rifle feel more nimble and easier to maneuver, especially during prolonged shooting sessions. For competitive shooters, hunters who spend long days afield, or individuals prioritizing a lightweight configuration, this can be a significant benefit.
Aesthetics
Aesthetically, an AR upper without forward assist can present a cleaner, more streamlined appearance. The absence of the plunger and its surrounding hardware creates a smooth profile on the upper receiver. Some shooters find this look more appealing, especially when paired with certain handguards or rail systems. In a world of customization, where aesthetics are paramount for some, this design choice is often a matter of personal preference, enhancing the visual appeal of the rifle to some.
Simplicity
Simplicity is another key advantage. Fewer parts translate to fewer potential points of failure. While the forward assist is generally a reliable component, its absence removes one more item that could potentially break or malfunction. This inherent simplicity contributes to ease of cleaning and maintenance. The reduced number of nooks and crannies simplifies the cleaning process.
Compatibility
Another benefit comes in the realm of compatibility. Removing the forward assist can increase compatibility with certain handguards or rail systems. The forward assist mechanism can sometimes interfere with the design or installation of specific aftermarket components. Eliminating the forward assist frees up space and streamlines the process. This can be particularly advantageous if you intend to use a handguard that fully encloses the upper receiver or a handguard design that is specifically built to eliminate interference with the forward assist.
Disadvantages of an AR Upper Without Forward Assist
Loss of Manual Assistance
The most significant potential disadvantage is the loss of a manual mechanism for forcing the bolt carrier group into battery. Without the forward assist, you don’t have a direct means of manually assisting the chambering of a round. While malfunctions are infrequent in well-maintained and reliable AR-15s, the forward assist can sometimes be useful in overcoming minor resistance, such as from a slightly oversized cartridge or a small amount of debris. Removing the forward assist does, therefore, require a greater reliance on the inherent reliability of the rifle.
Reliance on Reliability
This increased reliance on reliability highlights the critical importance of using high-quality components. It emphasizes the need to use a reliable bolt carrier group (BCG), a well-designed barrel, and, of course, quality ammunition.
Dealing With Malfunctions
Another consideration involves the mental aspect of a malfunction. Without a forward assist, if you encounter a failure to chamber, you will need to clear the malfunction manually (e.g., by retracting the charging handle and ejecting the round), or resolve the mechanical issue directly, which may include taking the weapon out of battery.
Aesthetic Concerns
Finally, the appearance of an AR upper without forward assist may not appeal to everyone. Some shooters simply prefer the “complete” look of an upper receiver with the forward assist. The absence of the forward assist can alter the visual balance of the rifle. This preference is, undeniably, subjective and a matter of personal taste.
Considerations for Choosing an AR Upper Without Forward Assist
Intended Use
One of the most important factors is your intended use for the rifle. If you plan to use your AR-15 for self-defense, where reliability is paramount, you need to carefully assess the benefits and drawbacks. If your usage is limited to recreational shooting, the absence of the forward assist may be less concerning, provided your rifle is meticulously maintained. The forward assist can be a valuable feature for duty weapons where every second counts.
Component Quality
The quality of the components you use in your build is absolutely critical, regardless of whether you opt for the forward assist. Prioritize a high-quality bolt carrier group. The bolt carrier group is the heart of your rifle’s cycling system. Ensure that you select a BCG from a reputable manufacturer known for their reliability. Also, ensure proper function with the barrel assembly, magazine and ammunition you are choosing.
Your Skill Level
Another consideration is your level of familiarity with the AR-15 platform. It is essential that you are capable of diagnosing and clearing malfunctions in an AR-15. Learn the proper procedures for dealing with failures to chamber, such as a bolt over base malfunction. Knowing how to quickly and safely address such issues without relying on the forward assist can be critical in certain scenarios.
Maintenance
Proper maintenance and lubrication are even more critical for an AR upper without forward assist. With the absence of the forward assist, meticulous cleaning and lubrication become all the more vital for ensuring reliable operation. Regular cleaning, including thorough inspection of the chamber and bolt carrier group, is essential. Proper lubrication, using quality gun oil, ensures smooth cycling and reduces friction.
Alternatives to the Forward Assist
Quality Build
Even when choosing an AR upper without forward assist, there are methods that can help prevent malfunctions. These can serve as a viable substitute for the forward assist’s function. These can include solutions or best practices that contribute to the reliability of your platform.
The primary alternative to the forward assist is reliance on the design of your AR platform and the quality of the components. A well-built AR-15, with a reliable bolt carrier group, quality barrel, and proper lubrication, should function flawlessly in most circumstances.
Magazine Selection
Quality magazines are also essential. Using magazines that feed reliably is paramount to avoiding malfunctions. Ensure your magazines are in good condition and that they properly interface with your rifle.
Conclusion
Choosing between an AR upper without forward assist and one that includes the component is a decision that hinges on your individual needs, priorities, and shooting style. The forward assist offers advantages, such as weight savings, a sleek aesthetic, and fewer parts. It carries the potential for added compatibility. However, there are some drawbacks. Weighing these factors carefully is crucial to making the right choice.
Ultimately, the best AR-15 configuration for you is the one that best aligns with your specific goals. Whether you choose to include a forward assist or not, the key is to build a rifle that is reliable, well-maintained, and perfectly suited to your intended use.
