The MDT Bolt On Arca Swiss Rail brings the modularity and precision of the Arca Swiss standard to any rifle with M-LOK slots on the handguard or forend. If you're running a precision rifle setup and want to leverage Arca-compatible tripods, monopods, and shooting bags without replacing your entire chassis, this bolt-on adapter is the straightforward solution. Built from 6061-T6 aluminum and hardcoat anodized for durability, it attaches securely to Magpul MOE spaced and tapped holes and maintains solid indexing through drilled and tapped mounting points.
Arca Swiss rails have become the standard for long-range and precision shooting because they allow you to dial in your position for difficult angles, swap stabilization gear in seconds, and position your tripod closer to the rifle's center of gravity. The MDT design includes thoughtful details: rounded edges that won't bite your hand during offhand shooting, an angled front surface that engages tripod heads smoothly and reduces the risk of snagging on brush or pack gear, and enough rearward overhang to keep your support system balanced. The solid M-LOK boss is engineered to handle repeated recoil without flex or creep.
This rail is compatible with the RRS dovetail standard, so you can attach a wide range of aftermarket Arca accessories from premium tripod heads to shooting rest components. Whether you're building a dedicated long-range rig, upgrading a competition rifle, or retrofitting an existing handguard, the Bolt On Arca Swiss Rail gives you the flexibility to integrate professional-grade support gear without committing to a complete platform change.

Frequently Asked Questions
Will this work on my rifle's handguard?
The MDT Bolt On Arca Swiss Rail attaches to handguards and forends that feature Magpul MOE spaced and tapped holes. If your handguard or forend has those mounting points, this rail will bolt on securely.
What tripod heads and accessories are compatible?
This rail is compatible with the RRS (Really Right Stuff) dovetail standard, which means it works with Arca Swiss tripod heads, monopods, and shooting rest bases that follow that specification. Check your tripod head or accessory documentation to confirm Arca Swiss compatibility.
Can I use this on an MDT ESS Chassis?
MDT offers foregrip Arca Swiss rails designed specifically for the ESS Chassis. This Bolt On model is designed for handguards and forends with M-LOK mounting; check your chassis manual to determine which version suits your setup.
How does the angled front surface help?
The angled front makes it easier to engage and seat tripod heads smoothly while reducing the chance that the rail will catch on brush, pack gear, or other equipment in the field—a practical advantage during setup in rough terrain.
