The forward assist is a small but crucial feature found on many modern semi-automatic rifles, most notably the AR-15 platform. While often misunderstood, its function is simple yet vital to reliable firearm operation. This guide will delve into the purpose, proper usage, and potential misconceptions surrounding the forward assist.
Understanding the Role of the Forward Assist
The forward assist's primary function is to ensure complete chambering of a cartridge. In simpler terms, it helps push a round fully into the chamber if it's slightly out of alignment or hasn't fully seated during the normal cycling process. This can occur due to various factors, including:
- Ammunition issues: Slightly undersized or improperly lubricated cartridges can sometimes fail to fully chamber.
- Mechanical malfunctions: Issues with the bolt carrier group or other internal components might impede complete chambering.
- Operator error: Improper handling or a failure to properly seat a round can also cause this problem.
When a round doesn't fully chamber, the rifle will typically fail to fire, leading to a malfunction. This is where the forward assist comes into play. By applying controlled force, it positively pushes the cartridge into the chamber, resolving the malfunction and allowing for a successful firing sequence.
How to Properly Use the Forward Assist
Using the forward assist is straightforward. However, it's crucial to do so correctly to avoid potential damage to the firearm.
1. Identify the Forward Assist: Locate the small, usually upward-facing protrusion located on the upper receiver, just above and behind the ejection port.
2. Ensure the Safety is Engaged: Always engage the safety selector before manipulating the forward assist. This prevents accidental discharge.
3. Apply Firm, Controlled Pressure: Depress the forward assist firmly, but avoid excessive force. A sharp, controlled push is sufficient. Do not slam or force it.
4. Cycle the Action: After using the forward assist, cycle the charging handle to ensure the round is fully seated and the weapon is ready to fire.
When Not to Use the Forward Assist
It's important to note that the forward assist is not a solution for all malfunctions. Over-reliance on the forward assist can indicate a more significant underlying problem. Excessive use suggests a need for professional inspection and maintenance of your firearm. Some situations where using the forward assist might be inappropriate or ineffective include:
- Double Feeds: These malfunctions involve two cartridges attempting to enter the chamber simultaneously. Forcing the forward assist in this situation can exacerbate the problem.
- Failure to Eject: If the spent cartridge casing isn't ejecting properly, the forward assist won't address the root cause.
- Broken or Damaged Parts: Attempting to force a round into a chamber with a broken extractor or other damaged components can cause further damage.
In cases of repeated malfunctions, consult a qualified gunsmith or armorer to diagnose and repair any underlying issues.
Common Misconceptions about the Forward Assist
- It's needed for every shot: The forward assist is a tool for correcting malfunctions, not a necessary part of every firing sequence.
- It can fix all malfunctions: The forward assist only addresses specific malfunctions related to incomplete chambering.
- Excessive force is beneficial: Overuse or excessive force can damage components within the firearm.
Conclusion: A Valuable Tool, Used Responsibly
The forward assist is a valuable tool for correcting specific malfunctions in semi-automatic rifles. Understanding its proper use, limitations, and potential issues will contribute significantly to safe and reliable firearm operation. Remember, consistent maintenance and professional inspection are key to preventing malfunctions in the first place, minimizing the need for the forward assist.
