Brownells Gun Tech™ Caleb Savant gives up a little love for one of the least-understood parts of the AR-15 rifle. No, he's already explained the forward assist.... We're talking about the DUST COVER over the ejection port! The dust cover is there to prevent dirt, debris, and dust from getting into the firearm's action while you're carrying it or transporting it. When you're actually shooting the rifle, the force of the ejection gases will keep dust and dirt out of the action. The military needs the dust cover on their M16s and M4s because of the dusty environments they may be operating in, like Iraq and Afghanistan. The semi-auto AR-15 is not the exact same gun, but it does have an exposed bolt carrier, too, hence a dust cover is included on most civilian ARs. For sport and competition AR-15 shooters, the dust cover is probably not strictly necessary. But it's there if you need it. In fact, the Kalashnikov AK-47 / AK-74 series of rifles actually has TWO dust covers, one on top of the receiver and the selector lever actually serves as a dust cover.
