In the world of firearms, especially with the ubiquitous AR-15 platform, understanding the mechanics of your weapon is paramount for both safe and effective operation. One component often discussed, sometimes lauded, and occasionally misunderstood, is the **forward assist**. This article will delve deep into the world of the **forward assist**, providing a comprehensive guide to its function, historical context, proper use, and potential limitations.
The AR-15, and its military counterpart the M16, are undoubtedly some of the most popular and versatile firearms in the world. Its modularity, adaptability, and ease of use have made it a favorite among civilians, law enforcement, and military personnel. But with such widespread use comes the need for a thorough understanding of every aspect of the rifle’s operation, from the trigger to the muzzle. This includes understanding even the smallest of parts, such as the forward assist.
The **forward assist** is a small, usually knurled, button located on the right side of the upper receiver of an AR-15 or M16 rifle. Its purpose, as its name implies, is to *assist* the bolt carrier group in moving forward, specifically seating the bolt into the chamber. It is a specific feature designed to address certain malfunctions, and it’s important to understand when it is most useful and when it can be counterproductive.
Now, let’s explore the history of this seemingly simple but often debated component.
Historical Context of the Forward Assist
The story of the **forward assist** is intricately linked to the early history of the M16 rifle. The M16, designed by Eugene Stoner and initially adopted by the United States military in the early 1960s, was a revolutionary weapon for its time. It was lighter, more controllable, and fired a smaller caliber round than the rifles it was meant to replace. However, the early M16s encountered some issues in the field.
One of the primary problems was reliability. Early versions of the M16 suffered from failures to feed, chambering issues, and other malfunctions. This was exacerbated by several factors, including:
Unproven Ammunition
The initial ammunition used with the M16 was not as clean-burning as it should have been, leading to carbon buildup in the chamber and bolt.
Insufficient Cleaning Practices
There were concerns about the level of cleaning and maintenance being done by troops in the field.
Chamber Dimensions
The early chambers had tighter tolerances than older platforms.
These issues could result in the bolt not fully closing, preventing the rifle from firing. The military, seeking to resolve these problems, began looking for a solution. The primary objective was to make sure the rifle was able to consistently load and fire a round.
This is where the **forward assist** comes in. It was designed to address these issues by allowing the operator to manually push the bolt carrier group forward and ensure the bolt was fully seated. This would hopefully ensure that the weapon would fire. The development timeline centered around the Vietnam War. The issues that were experienced during the war showed there was a need for a manual override in case of malfunction.
The **forward assist** was quickly added to the M16’s design, and has remained on the platform ever since, becoming a defining feature of the AR-15 family. It was meant to be a quick fix for a variety of issues.
However, the times have changed, and the AR-15 world has evolved. Modern AR-15s have benefitted from improvements to ammunition, manufacturing, and quality control. The **forward assist** is still found on virtually all AR-15s, but its necessity is often debated in today’s world.
Function of the Forward Assist
Let’s dive deeper into how the **forward assist** actually works.
The core components of the **forward assist** are a button (usually knurled for a better grip), a pawl (also called a “ratchet” or “dog”) which is a small, spring-loaded component, and a pin that holds the button and pawl in place. These components are mounted inside the upper receiver of the rifle.
When the button is pressed, the pawl engages with the grooves on the bolt carrier. As you press down on the button, the pawl rotates and grips the bolt carrier. This direct mechanical connection allows the user to apply force to push the bolt carrier group forward and into battery. This action ensures the bolt is completely closed and seated within the chamber.
The function of the **forward assist**, in essence, is to bridge the gap between a partially closed bolt and a fully closed, ready-to-fire position. It’s meant to overcome minor resistance to the bolt’s forward movement and force the bolt into a fully locked position. This, ideally, allows the firing pin to strike the primer and fire the round.
It is critical to understand what the **forward assist** *cannot* do. It is not a magic bullet that solves all firearm malfunctions.
It cannot clear a jammed cartridge
If a spent casing or unfired round is stuck in the chamber, the forward assist will not clear it. It may make it worse by seating the bolt on top of the malfunction.
It does not replace proper maintenance
Neglecting to clean your rifle regularly will lead to malfunctions. The forward assist is not a substitute for a well-maintained firearm.
It is not designed to fix severe malfunctions
Serious mechanical problems or ammunition issues require a different approach, not the use of the **forward assist**.
The primary goal of the **forward assist** is to ensure the bolt is properly seated, a crucial step for safe and reliable firing.
When to Use the Forward Assist
Knowing when to use the **forward assist** is as crucial as knowing how it works. It’s about making informed decisions based on the situation.
There are some situations where the **forward assist** may be helpful:
Failure to fully chamber a round
If the bolt carrier group is only slightly out of battery, the forward assist may be able to push it the remaining distance. This is usually caused by a slightly dirty chamber, slight variations in ammunition dimensions, or a weak recoil spring.
Light failures of the bolt to close
Sometimes, the bolt may not close completely due to a little bit of resistance. The **forward assist** can assist in these situations. This can be a result of minor dirt or debris.
Cold weather or ammunition issues
Some ammunition, particularly in cold temperatures, may generate slightly less gas pressure, which can affect the bolt’s ability to cycle fully. In these scenarios, the **forward assist** might provide the necessary push.
However, there are also situations where using the **forward assist** is *not* advisable or can even be detrimental.
If the bolt is obstructed by a spent casing or a live round that’s not properly seated, forcing the bolt closed with the **forward assist** could cause a catastrophic malfunction, potentially damaging the rifle or causing injury.
If the rifle is experiencing repeated malfunctions, the operator needs to diagnose the root cause of the problem, instead of just relying on the **forward assist**. Continued reliance on the **forward assist** without identifying and fixing the issue could lead to a dangerous situation.
It is of paramount importance to diagnose and solve the underlying problem. Relying on the **forward assist** without finding and fixing the source of the malfunction is a short-sighted approach that will ultimately create problems.
Common Misconceptions and Debates
The **forward assist** has a lot of myths surrounding it. One of the most common myths is that it’s always necessary or that it’s a crucial component for the AR-15. While the **forward assist** has its place, it’s not a mandatory part of every AR-15 setup.
The debate over the **forward assist**’s necessity stems from the fact that in modern AR-15s, many of the issues that the **forward assist** was designed to address have been mitigated. Today’s firearms are better built, with tighter tolerances, and modern ammunition is cleaner-burning.
This is where you often see the argument about “do you *need* it?” Some builders and enthusiasts choose to omit the **forward assist** from their builds, viewing it as an unnecessary component that adds complexity. This decision can shave a small amount of weight and streamline the rifle’s appearance.
There are alternative solutions and approaches that may reduce the need for the **forward assist**, such as:
Proactive maintenance
