The forward assist is a small but crucial component found on many modern semi-automatic and select-fire rifles, most notably the AR-15 platform and its variants. Understanding its function, proper usage, and potential drawbacks is vital for anyone handling these firearms. This comprehensive guide will delve into the intricacies of the forward assist, clarifying its purpose and addressing common misconceptions.
The Purpose of a Forward Assist
The forward assist's primary function is to assist in chambering a round when the bolt fails to fully go into battery. This can happen due to various reasons, including:
- Improper ammunition: Malfunctioning or slightly out-of-spec ammunition can hinder smooth chambering.
- Dirt, debris, or malfunctions: Foreign material in the receiver or a slight mechanical issue can prevent the bolt from fully closing.
- User error: Improper handling or manipulation of the charging handle can sometimes lead to incomplete chambering.
Essentially, the forward assist provides a final push to ensure the round is securely seated in the chamber, ready for firing. It's a safety mechanism designed to prevent potential misfires or malfunctions caused by partially chambered rounds.
How a Forward Assist Works
The forward assist is typically a small, spring-loaded lever located on the right side of the upper receiver, just above the ejection port. When activated, it forcefully pushes the bolt carrier group (BCG) forward, ensuring complete chambering of the cartridge. Its operation is relatively simple and straightforward, requiring minimal force to engage.
Step-by-Step Activation:
- Identify the forward assist: Locate the small lever on the upper receiver.
- Check for obstructions: Ensure there are no obstructions preventing the bolt from closing.
- Engage the forward assist: Firmly push the lever forward until it clicks. This action will push the BCG forward, chambering the round.
- Check for proper chambering: Visually verify that the round is fully seated in the chamber.
When Not to Use the Forward Assist
While the forward assist is a helpful tool, over-reliance or improper use can lead to problems. It should not be used routinely. Repeated use might indicate a more serious underlying issue, such as:
- Dirty or malfunctioning BCG: Consistent need for the forward assist suggests a cleaning or maintenance requirement.
- Ammunition problems: Using unreliable ammunition will constantly necessitate the forward assist.
- Damaged parts: Worn or damaged components within the firearm may contribute to incomplete chambering.
Using the forward assist frequently may also contribute to wear and tear on the firearm's components. If the forward assist is regularly required, it's crucial to investigate and address the root cause of the malfunction rather than continuously relying on the assist.
Forward Assist: Pro's and Con's
Pros:
- Increased reliability: Provides a backup mechanism for reliably chambering rounds.
- Safety enhancement: Helps prevent misfires and malfunctions caused by incomplete chambering.
- Simple operation: Easy to use and understand, even for novice shooters.
Cons:
- Potential for wear and tear: Overuse can contribute to premature wear and tear of firearm components.
- False sense of security: May encourage neglecting proper maintenance and cleaning.
- Not universally found: Not all rifles feature a forward assist, meaning users need to adapt to different methods of addressing chambering issues.
Conclusion
The forward assist is a valuable feature on many rifles, offering a safety net for potentially problematic chambering issues. However, it's crucial to remember that it's a tool of last resort and not a substitute for proper firearm maintenance and the use of quality ammunition. Understanding its function and limitations ensures its effective and safe utilization. Regular cleaning, proper lubrication, and the use of quality ammunition are far more effective at preventing malfunctions than repeatedly using the forward assist.
