The FN SCAR 20S has earned its reputation as one of the most accurate and reliable long-range precision rifles on the market, and enhancing its performance starts with choosing the right accessories. Whether you’re setting up for competitive shooting, tactical applications, or simply refining your precision platform, selecting gear designed specifically for this rifle ensures optimal results.
At Kinetic Development Group, shooters will find a specialized lineup of enhancements crafted for the FN SCAR 20S platform. These aren’t one-size-fits-all add-ons—they’re precision-engineered upgrades made to improve ergonomics, modularity, and performance.
Why Accessorizing Your FN SCAR 20S Matters
Precision rifles like the FN SCAR 20S benefit significantly from quality aftermarket parts that complement the rifle’s intended use. For those focused on modularity and customization, the right rail system, optics mounting solution, or magazine can make a significant impact on performance and usability. Kinetic Development Group provides an array of options tailored to this exact rifle, making it easier to fine-tune your loadout.
Feature-Rich Rail Systems for the FN SCAR 20S
One of the most impactful upgrades available is the MREX20 series rail system. Designed specifically for the FN SCAR 20S, these rails are constructed from aircraft-grade aluminum and finished with a non-infrared reflective Cerakote. They offer a lightweight yet durable mounting platform for M-LOK-compatible accessories like bipods, grips, lights, or lasers.
The MREX20 is available in several configurations:
- The MREX20 XL, which adds 3.5 inches of extra rail space for extended hand placement or accessory mounting.
- The MREX20 A, incorporating an integrated Arca-Swiss rail—ideal for tripod shooters looking for seamless interface with their support gear.
- The MREX20 AXL, combining both the longer profile and Arca interface for maximum flexibility.
These options are engineered to reduce weight while improving the rifle’s handling and balance. For shooters looking to enhance their control and comfort, the MREX20 series is a must-consider upgrade.
Enhanced Magazine Design for Consistent Performance
KDG’s KA2-20 magazine was developed in partnership with Amend2 to address both durability and function. Compatible with FN SCAR 17 and 20S rifles, these 20-round magazines use an impact-resistant polymer body and a stainless steel spring for long-term reliability. Features like anti-tilt followers and textured grip surfaces give users more confidence during reloads and handling in challenging conditions.
Having consistent feeding and easy handling is essential, especially for long-range sessions where every round matters. You can check out the KA2-20 SCAR Mag Bundle on the KineticDG product page for current bundles and availability.
Practical Tools for On-the-Go Adjustments
KDG also offers a SCAR-specific tool kit built around the Fix It Sticks modular system. This portable kit includes torque limiters, bits, and drivers you’ll actually use—no filler, no gimmicks. It’s tailored for the kind of adjustments SCAR owners frequently make, like rail swaps, scope tightening, and lower receiver maintenance.
Pair that with their QD sling mounts and 45/90 safety selectors, and you’ve got a rifle that’s more comfortable to carry and easier to control—especially in dynamic shooting environments.
