Similarities Between the AR-15 and M4

Despite their differences, the AR-15 and the M4 are extremely similar. They use many of the same components, such as the same charging handle, trigger assembly, many parts of the upper and lower receiver, and the bolt carrier group. You can even use the same handguards and rail systems as well. In sum, if you pick up either firearm, you will be able to operate each one swimmingly.

Currently with the military moving towards an MLOK rail system as the new normal for all rifles, they are finally catching up with the civilian market. The civilian market pushes innovation even if it doesn't need to for the current target audience. Now a service member who is receiving an MLOK-equipped rifle can purchase more aftermarket parts for their service rifle. 

Difference Between M4 and Ar15

The M4 could be more accurately described as the carbine version of the M16, which is the military version of the AR-15. The AR-15 is one of the most popular firearms in the United States — and for good reason. They get the job done, they are great for self-defense, they are fun to shoot, and they are completely customizable so you can create the firearm that fits you perfectly, which is super important for accurate firing. Since everybody is different, having the ability to create a firearm that fits your grip, stance, hold, height, and other unique features is huge in many people's books and why they are attracted to such a firearm.

Both the AR-15 and M4 platforms are known for their customization options. RailScales offers products in every category that can help to fine-tune a rifle to the individual user. Whether a forward control device like the Karve or RSBM-P, grip panels to help knock down heat transfer from the barrel like the XOS RailScales, or even optimized sling mounting options like the QDX, RailScales has a solution for virtually any shooter. With it's modularly designed products able to fit both short and long rails, and incremental scale sizes ranging from 1 Slot, 1.5 Slot, 2 Slot, 2.5 Slot, 3 Slot and 4 Slot options, customization comes easy with RailScales products. 

With MLOK being widely used now across all platforms, military and civilian, RailScales has a bigger audience to appeal to. With our MLOK line of rail panels and control items such as the RSB and Anchor, it doesn't matter what rifle you are using, M4 or AR-15, we have what you need.
