M-LOK – 2-Piece Rail Mount Combo – 3-Slot and 7-Slot – Black
The Sylvan Arms RC100 combo pack gives you both a 3-slot and 7-slot quick-detach Picatinny-to-M-LOK rail setup in one kit. Built from black anodized 6061-T6 aluminum, it is meant for fast attachment and removal without tools when you need to swap accessory layouts on the fly.
Simple idea: more flexibility, less permanent nonsense hanging off the rifle.
Fitment
- Fits M-LOK compatible rails and handguards
What it does
This combo kit gives you both a shorter and longer Picatinny mounting option for lights, grips, or other rail-mounted accessories on M-LOK platforms.
Why it’s worth it
If you actually change rifle setups instead of pretending you do, this kit makes sense. The 3-slot and 7-slot mix gives better placement flexibility than buying only one size.

Install notes
Mount to compatible M-LOK slots and verify each section is fully retained before mounting accessories. Plan slot spacing before setup so you do not stack gear where your support hand still needs to exist.
Verify before you buy
Verify you want the 2-piece rail combo and not the 3-piece rail-and-sling combo. Also verify your handguard is M-LOK.
