When in transport, end caps are often placed over the flash suppressor. The M16 and M4 are actually fairly well resistant to the intrusion of dirt and other foreign objects. When not in use, a dust cover goes over the ejection port. Additionally, the tolerances of the M16/M4s design assures a pretty tight fitting of the bolt carrier inside the receiver. There isn't space for dirt to get in through the ejection port while the bolt carrier is in the forward position. Additionally, service members lube their weapons lightly, as excessive lubricants will attract and hold dirt. Above all, routine maintenance is performed - weapons must be cleaned and maintained regularly.
Port Talbot has mountains to the north and the sea to the south. To the east and the west you get the ribbon-development which stretches all along the M4.
