FN SCAR® Accessories & Upgrades Overview

FN SCAR® accessories and upgrades at FN Specialties include modular receivers, trigger modules, bolt carriers, rails, triggers, grips, and sling solutions. Compatible with SCAR® 16S, 17S, 20S, and 15P, these enhancements deliver improved ergonomics, recoil control, and customization potential for one of the most versatile rifles on the market.

Game-Changing Cypher Upgrades for the FN SCAR®

The Cypher Modular System provides unmatched flexibility and performance for the SCAR® platform. Options include:

• Cypher Receiver for SCAR® 16S and CypherX Receiver for SCAR® 17S — Lightweight, durable, and available in multiple configurations, these receivers expand modularity while maintaining SCAR® compatibility.
• Cypher MTM Lower — An aluminum lower that replaces proprietary FN parts with AR-pattern compatibility. Accepts AR triggers, selectors, grips, and SR-25 magazines for superior ergonomics and customization.
• Cypher Buffered Bolt Carrier — Reduces recoil, prevents over-gassing when suppressed, eliminates bolt bounce, and protects receiver surfaces. Compatible with NRCH conversions when paired with the Cypher Charging Sled, NRCH handles, and front NRCH plate.

FN SCAR® Trigger Upgrade

The Geissele Super SCAR Trigger is one of the most sought-after SCAR® upgrades. This two-stage trigger provides a crisp, consistent break with minimal overtravel and a reset designed for speed. With an optimized pull weight around 4 pounds, it offers a major improvement over the heavier stock trigger. Note: The Super SCAR is only compatible with the factory SCAR® trigger module. Cypher MTM users can select from any standard AR-pattern trigger.

FN SCAR® Rails & Handguards

Accessory rails expand mounting capability and improve control. The KDG MREX M-LOK MK2 Rail is a lightweight, aircraft-grade aluminum option that adds M-LOK® slots for lights, lasers, and grips while maintaining a low profile and stable fit.

FN SCAR® Grips

Upgrading grips enhances comfort and control for extended shooting. Recommended options include:

• Ergo 2 SCAR Grip — Comfortable angle with soft rubber texture for fatigue-free control.
• Magpul AFG Fore Grip — Angled foregrip that promotes natural wrist position and improved stability.
• Magpul AFG-2 Fore Grip — Slimmer, streamlined version of the AFG with ergonomic shaping.

FN SCAR® Slings & Mounts

A quality sling transforms the SCAR® into a more controllable and versatile rifle. FN Specialties offers a wide selection of SCAR-compatible slings, giving you the flexibility to choose the attachment style and configuration that fits your needs. Options include:

• Two-Point Bungee Sling with Mash Hooks — Connects directly to factory SCAR® sling loops with no modifications.
• Single-Point Non-Bungee Sling and Single-Point Bungee Sling — Provide maneuverability and rapid transitions between carry positions.
• Convertible One/Two-Point Non-Bungee Sling and Convertible One/Two-Point Bungee Sling — Adjustable designs that switch easily between single- and two-point carry.

QD sling attachment options include the KDG Rear QD Point, KDG Front Ambidextrous QD Point, Tactical Link Gen 2 Rail QD Mount, and Magpul RSA QD Rail Sling Attachment. These hardware solutions expand versatility and make any of our slings a seamless fit for your SCAR® rifle.
