They both have their fans, but there are some important differences between them that you should know before making a purchase. In this article, we’ll take a look at the key differences between these two rifles and help you decide which one is right for you. Happy shooting.

The AR-15 and the M4 are both popular rifles in the United States, but there are some significant differences between them. The AR-15 is a more versatile rifle that can be used for a variety of purposes, while the M4 is shorter and more lightweight, making it better suited for close-quarters combat. There are pros and cons to both rifles, so deciding which one is right for you depends on your individual needs.

Some people believe that an AR-15 is interchangeable with an M4. This couldn’t be further from the truth, as they’re two entirely different weapons. The AR-15 is a semi-automatic rifle (meaning it shoots one bullet per trigger pull) and can accommodate magazines up to 30 rounds in size. The M4, on the other hand, is a fully automatic weapon that fires continuously when you hold down the trigger and also has a standard capacity of 30 rounds per magazine.

The m4 and AR15 are two rifles that share a lot of similarities. They’re both lightweight, gas-operated, magazine-fed semi-automatic firearms with rotating bolts. However, there are key differences between the two weapons that make them very different from one another. The main difference is that the M4 has a 14.5-inch barrel while the AR15 has a 16-inch barrel which makes it more accurate and lethal at longer ranges than its shorter counterpart.
