Quick Detach M-LOK Picatinny Rail Section, 7 Slot

A good rail section should give you options, not extra hassle.

The Sylvan Arms QDR300 is built for shooters who want to add Picatinny mounting space to an M-LOK handguard quickly and remove it just as easily when the setup changes. Instead of treating a rail section like a permanent commitment, this design gives you the flexibility to run the space you need, when you need it.

With seven Picatinny slots, the QDR300 gives you a practical amount of room for compatible accessories while keeping the profile clean and lightweight. It is made from 6061-T6 aluminum, finished in black anodizing, and weighs just 1.4 ounces, so it adds function without making the front end of the rifle feel bulky or overbuilt.

If you like to fine-tune your setup, move accessories between rifles, or simply want a more convenient way to adapt an M-LOK handguard, this is the kind of upgrade that makes sense the first time you use it.

Why shooters choose the QDR300

Some rail sections are meant to stay in one place forever. This one is different. The QDR300 is designed for shooters who want speed, flexibility, and a setup that can adapt without turning a simple change into a project.

The quick detach design makes it easy to add a 7-slot Picatinny section when needed and remove it when you want a cleaner handguard. That makes it a smart choice for modular rifle builds, changing range setups, or anyone who wants more control over how their rifle is configured.
