Any modern firearm needs to have a certain degree of modularity. It should be able to mount various optics, grips, light lasers, and other accessories. Most firearms these days come with accessory rails, and M-LOK and Picatinny rails are the two most common mounting platforms.

If you have an M-LOK compatible handguard and want to mount some of your Picatinny accessories on it, you need to have an adapter rail. The Ergo 5-Slot M-LOK Cantilever Low-Pro U.M.P. Rail is an excellent option. It allows you to mount Picatinny accessories on an M-LOK slide, and above that, it can also extend your mounting capabilities.

By mounting this 5-slot rail on the front end of your handguard, you can mount accessories like flashlights much closer to the muzzle. This improves low-light visibility with the sight since the shadow of the muzzle doesn't obstruct your vision.

To ensure durability, this rail is made from 6061 T6 Aluminum and has a Type III Class 2 Hardcoat Anodized. As a result, this rail can easily handle the weight of any lights, lasers, or other accessories you throw at it.
