What is a forward assist on an ar-15?

The forward assist is a feature found on the AR-15 rifle and its variants. It is typically located on the right side of the upper receiver, just behind the ejection port cover. The forward assist is a small button or lever used to manually close and lock the bolt into battery.

The primary purpose of the forward assist is to assist in chambering a round in cases where the bolt does not fully close or lock due to dirt, debris, or other obstructions. In rare situations, the bolt may not fully chamber a round during normal operation, and the forward assist allows the user to force the bolt forward securely, ensuring proper functioning and firing.

Using the forward assist is easy, as it typically only requires a push or hit on the button or lever to engage. After a round has been chambered, the forward assist can also be used to double-check and ensure that the bolt is fully in battery before firing.

However, it's important to note that the forward assist should not be used as a regular operating procedure. The AR-15 rifle is designed to be a reliable firearm and typically does not require the use of the forward assist during regular shooting or maintenance. Excessive or unnecessary use of the forward assist can potentially cause damage or malfunctions to the rifle.

Many modern AR-15 versions no longer include the forward assist, as advancements in weapon design, manufacturing, and ammunition have significantly reduced the need for it. Nonetheless, some variants or older models still retain this feature as it provides an option for manually ensuring the rifle is fully loaded and ready to fire.
