Building out an M-LOK handguard usually means fishing for the right hex key and taking your time. The Sylvan Arms 3-Piece QD M-LOK Rail & Sling Mount does away with that. Using the company's patented Rapid Attach Mounting System, you squeeze the two extended arms, drop the piece onto your rail, and let go. No tools, no fuss, and it locks in solid. When you want to reposition something or move it to a different rifle, you just do it again.
This combo covers three of the most common jobs on a modern rifle. You get a 3-slot Picatinny section (QDR100) for smaller add-ons like a light or a laser, a 7-slot Picatinny section (QDR300) for bigger gear that needs more real estate, and a dedicated QD sling mount (QDR200). The sling piece is the versatile one of the bunch since it accepts a push-button QD swivel or a standard clip-style sling loop, so it plays nice with just about whatever sling you already run.
The real appeal here is speed and flexibility on the fly. Whether you're making adjustments at the range, dialing in a setup in the field, or running drills, being able to reposition your grip surface or sling point in seconds is a genuine time-saver. Since every piece indexes to standard M-LOK slots, you can spread them across the handguard exactly where your hands and gear want them.
Each piece is machined from 6061-T6 aluminum and finished in a black anodized coating, so they're light and hold up to hard use without adding noticeable bulk. The 3-slot mount runs about 0.8 oz, the sling mount about 1 oz, and the 7-slot mount about 1.4 oz. It's a practical, no-nonsense kit for anyone who likes to tinker with their rifle layout without keeping a toolbox on the bench.
No tools are required. Each piece uses Sylvan Arms' patented Rapid Attach Mounting System, so you squeeze the two extended arms, seat the mount on your M-LOK slots, and release to lock it in. Removing or repositioning works the same way and takes just seconds.
The QDR200 sling mount is built to accept either a push-button QD sling swivel or a standard clip-style sling loop. That flexibility means it pairs with most single-point and two-point slings on the market. You can also slide it to a different spot on the rail whenever your carry preference changes.
Yes, all three pieces are designed specifically for M-LOK compliant rails and index directly to standard M-LOK slots. As long as your handguard uses the M-LOK attachment system, you can mount these anywhere you have open slots. They will not fit KeyMod or standard Picatinny handguards.
The kit includes a 3-slot Picatinny section (QDR100) and a 7-slot Picatinny section (QDR300). The shorter 3-slot piece is handy for smaller accessories like a light or laser, while the 7-slot gives you more room for larger gear. Both add a stretch of Picatinny rail to your M-LOK handguard without permanent hardware.
