The AR-15 platform, a cornerstone of modern firearms, boasts a feature often misunderstood: the forward assist. This seemingly small component plays a crucial role in ensuring reliable operation, especially in less-than-ideal conditions. This article will delve into the function of the forward assist, explaining its purpose, when it's necessary, and dispelling common misconceptions.
Understanding the Forward Assist's Role
The forward assist is a small, lever-like mechanism located on the right side of the upper receiver, just above the ejection port. Its primary function is to assist in fully chambering a round that has not seated properly. This can happen due to several factors, including:
- Improper ammunition: Damaged or slightly deformed cartridges can fail to fully chamber.
- Dirty or malfunctioning firearm: Buildup of debris or malfunctions in the bolt carrier group can hinder proper chambering.
- Improper charging handle operation: Failure to fully cycle the charging handle can leave a round partially chambered.
When a round is not fully chambered, the bolt may be slightly out of battery—meaning it hasn't fully locked into place. This can lead to a failure to fire or a dangerous malfunction. The forward assist provides a forceful push to positively seat the round into the chamber, resolving this issue.
How the Forward Assist Works
The forward assist lever is pushed forward, impacting the bolt carrier group. This action applies a forward force that pushes the bolt fully into battery, firmly chambering the round. It's important to note that the forward assist should only be used when absolutely necessary. Overuse can contribute to wear and tear on the firearm.
When to Use the Forward Assist
You should only use the forward assist if you experience a failure to fully chamber a round. This is often indicated by:
- A visibly unseated cartridge: You can see the cartridge is not fully seated in the chamber.
- A failure to fire: The trigger is pulled, but the firearm does not discharge.
- Difficulty cycling the action: The charging handle feels stiff or resists movement.
If you encounter these issues, carefully attempt to gently cycle the charging handle again. If the problem persists, then and only then should you use the forward assist.
When NOT to Use the Forward Assist
It is crucial to emphasize that the forward assist is not a general solution for all malfunctions. Overusing it can damage your rifle. Never attempt to use the forward assist:
- As a substitute for proper cleaning and maintenance: Regularly cleaning and maintaining your AR-15 is crucial for reliable operation. Don't rely on the forward assist to compensate for neglect.
- If you don't know what is causing a malfunction: Attempting to use the forward assist without understanding the root cause of the malfunction can worsen the situation.
Dispelling Common Misconceptions
A frequent misconception surrounds the forward assist: some believe it's essential for every single loading. This is inaccurate. A properly functioning AR-15 should reliably chamber rounds without requiring the forward assist. Its role is purely supplementary, designed to assist in rectifying specific malfunctions.
Conclusion
The forward assist is a valuable tool on the AR-15 platform, providing a method to rectify a partially chambered round. However, it's crucial to understand its proper usage and avoid relying on it as a general fix-all solution. Proper firearm handling, regular maintenance, and understanding of potential malfunctions are paramount to safe and reliable operation. If you have persistent issues with chambering rounds, seek professional assistance from a qualified gunsmith.
