The AR-15 platform, a staple in modern firearms, boasts a range of features that contribute to its reliability and ease of use. One such feature, often misunderstood, is the forward assist. This seemingly small component plays a crucial role in ensuring reliable function, especially in challenging conditions. This article will explore what a forward assist is, how it works, when it's needed, and address some common misconceptions.
Understanding the Purpose of the Forward Assist
The forward assist is a small lever, typically located on the right side of the upper receiver, just above the ejection port. Its primary function is to assist in chambering a round that has failed to fully seat during the charging handle operation. This can happen for various reasons, including:
- Improper ammunition: A slightly dented or otherwise malformed round might not fully chamber.
- Dirty or damaged components: Buildup of debris in the chamber or a malfunctioning extractor can impede proper chambering.
- Improper charging handle manipulation: Failure to fully cycle the charging handle can leave the round partially chambered.
Essentially, the forward assist provides a supplementary push to fully seat the round into the chamber, preparing the rifle for firing.
How the Forward Assist Works
The forward assist is a simple yet effective mechanism. It's a small, spring-loaded plunger that, when depressed, pushes the bolt carrier group (BCG) forward, forcing the round firmly into the chamber. The action is typically accompanied by a noticeable click as the round fully chambers. It's important to note that the forward assist should only be used when a round is already partially chambered. Applying it to an empty chamber will not achieve anything and could even lead to unnecessary wear.
Step-by-Step Operation:
- Identify the Problem: Notice a round is partially chambered and the rifle will not fire.
- Engage the Forward Assist: Depress the forward assist lever firmly. You should feel resistance as the plunger engages.
- Check Function: After releasing the forward assist, check if the round is fully chambered and the rifle is ready to fire.
When to Use (and Not Use) the Forward Assist
While the forward assist is a valuable tool, it's crucial to understand when its use is appropriate. Overuse can contribute to wear and tear on the firearm. Here's a breakdown:
When to Use:
- Malfunctions: When a round fails to fully chamber during normal operation.
- Difficult Conditions: In adverse conditions (e.g., extreme temperatures, dust, mud), the forward assist can provide extra assistance.
When NOT to Use:
- Empty Chamber: Never use the forward assist on an empty chamber.
- Excessive Force: Excessive force is not necessary and can damage the firearm. A firm, controlled depression is sufficient.
- As a Routine: The forward assist is not a replacement for proper maintenance and ammunition selection. Don't rely on it to consistently overcome problems.
Common Misconceptions about Forward Assists
-
Myth 1: The forward assist is essential for function. This is incorrect. Many AR-15 variants function perfectly without a forward assist. The forward assist is an aid, not a necessity.
-
Myth 2: The forward assist fixes all malfunctions. The forward assist only addresses issues related to partially chambered rounds. It won't resolve problems with the trigger, firing pin, or other firearm components.
-
Myth 3: Using the forward assist is harmful. While overuse can contribute to wear, occasional use as intended will not damage a properly maintained firearm.
Maintenance and Upkeep
Regular cleaning and lubrication of the AR-15, including the bolt carrier group, will minimize the need to use the forward assist. A properly maintained rifle will reliably chamber rounds without assistance.
Conclusion: A Valuable but Supplementary Tool
The forward assist is a valuable tool on the AR-15 platform, assisting in the chambering of rounds that have failed to fully seat. Understanding its function, proper use, and limitations is key to maintaining a reliable firearm. Remember that it's a supplementary tool, not a primary solution for malfunctions. Proper maintenance, ammunition selection, and consistent practice remain crucial for safe and reliable operation.
