The forward assist is a small, often overlooked feature on many AR-15 and M16 style rifles, but understanding its function is crucial for safe and reliable operation. This guide will delve into the purpose, mechanics, and proper usage of the forward assist, dispelling common misconceptions and ensuring you're well-informed.
Understanding the Purpose of the Forward Assist
The forward assist's primary purpose is to ensure complete chambering of a round. It's a supplementary mechanism designed to aid in correcting malfunctions where the bolt carrier group (BCG) fails to fully seat a cartridge into the chamber. This can happen due to several reasons, including:
- Improper ammunition: Damaged or improperly sized ammunition can hinder smooth chambering.
- Dirty or damaged BCG: Buildup of debris or damage to the BCG can impede its movement.
- Operator error: Failing to properly manipulate the charging handle can result in incomplete chambering.
- Faulty parts: Worn or damaged parts within the firearm can also contribute to this problem.
The forward assist provides a forceful, controlled method to nudge the round fully into the chamber, resolving the malfunction and allowing the weapon to fire.
How the Forward Assist Works
Mechanically, the forward assist is a simple, yet effective device. It's a small lever located on the upper receiver, typically just above the ejection port. When engaged, it forcefully pushes the BCG forward, driving the round fully into the chamber. This action is typically accompanied by a noticeable click sound.
Important Note: The forward assist is not intended for routine use. It's a tool for addressing malfunctions, not a substitute for proper weapon maintenance and handling. Overuse can lead to unnecessary wear and tear on the firearm.
When (and When Not) to Use the Forward Assist
The forward assist should only be used when:
- You've experienced a failure to feed or chamber a round: If the weapon fails to cycle properly and you feel resistance, the forward assist can be used after troubleshooting other possible causes.
- You have confirmed a round is partially chambered: Do not use the forward assist if you are unsure of the round's position. Incorrect use could lead to injury.
Avoid using the forward assist when:
- There is a suspected stoppage outside of chambering issues: Jamming due to other issues should be addressed by clearing the malfunction through the standard malfunction clearing drills, not by using the forward assist.
- You're unsure of what the problem is: Attempting to solve an unknown malfunction with the forward assist could worsen the situation. Proper troubleshooting is key.
- As a matter of routine: This is critical! Consistent use puts unnecessary stress on your firearm and is not necessary for normal operation.
Maintaining Your Forward Assist
Like any part of your firearm, the forward assist requires proper maintenance. Keep it clean and free of debris to ensure its proper function. Regular cleaning and lubrication will help prevent malfunctions and extend the life of your firearm.
Conclusion
The forward assist is a valuable tool for addressing specific malfunctions, but it’s not a catch-all solution for every problem. Understanding its purpose, proper usage, and limitations is crucial for safe and reliable operation of your AR-15 or M16-style rifle. Remember, proper maintenance and handling are always paramount for safe firearm operation. If you're unsure about any aspect of firearm maintenance or operation, consult a qualified firearms instructor.
