M-LOK – 7-Slot Picatinny Rail Mount – Quick Detach – Black
The Sylvan Arms QDR300 is a quick-detach 7-slot Picatinny-to-M-LOK rail adapter built for fast attachment and removal without tools. It is made from 6061-T6 aluminum with a black anodized finish and gives you extra accessory mounting space when you need it without leaving permanent clutter on the gun.
Useful, clean, and a lot better than bolting random junk on your handguard like a yard sale special.
Fitment
- Fits M-LOK compatible rails and handguards
What it does
This mount adds a 7-slot Picatinny section to an M-LOK handguard for lights, grips, or other Picatinny accessories, with quick attach and removal capability.
Why it’s worth it
It gives you more flexibility without forcing you into a permanent rail section. Good for guys who swap accessory layouts depending on the rifle’s role.

Install notes
Attach to a compatible M-LOK slot and verify full retention before mounting accessories. Make sure the accessory footprint matches your available slot space and intended placement.
