Kinetic Development Group MREX15 Rail for the FN SCAR 15P

Kinetic Development Group (KDG) has introduced the MREX15, a compact rail system for the FN SCAR 15P. The company describes the MREX15 as a shortened variant of its MREX MKII rail, intended to improve ergonomics and utility on the SCAR 15P without increasing overall length.

FN SCAR @ TFB:

• The FN SCAR 15P Is Coming To The Consumer Market
• TFB REVIEW: FN SCAR 15P – The Civilian SCAR-SC
• A Farewell to SCAR: Was it Really That Amazing?

• Optimized Ergonomics: Despite its reduced length, the rail retains critical M-LOK mounting points, enabling users to attach tactical accessories while maintaining comfortable hand placement.
• Robust Construction: Machined from 6061-T6 aircraft-grade aluminum and finished with Type III hard-coat anodizing — available in black or FDE (Flat Dark Earth) — the rail is built for resilience in demanding conditions.
• Featherweight Design: At just 2.6 ounces, the MREX15 offers strength without unnecessary weight.
• Tailored Integration: The rail is compatible exclusively with the FN SCAR 15P and is 100% manufactured in the USA.
• Comprehensive Kit: Each unit includes the MREX15, M5-0.8 × 12 mm, 10 mm, and 6 mm fasteners, a mounting bridge, a T25 Torx wrench, and thread-locking compound (Vibra-Tite or equivalent).

According to KDG, the MREX15 was engineered to give shooters the edge:

• By keeping the rail flush with the receiver, the profile is less prone to snagging or interference.
• The lightweight yet rigid build reduces forward weight while preserving structural integrity under sustained use.
• M-LOK slots along the body allow selective attachment of lights, lasers, grips, or other systems, enabling configuration flexibility tailored to mission profiles.
• KDG’s track record as a pioneer in FN SCAR rail systems offers users confidence in performance, support, and accessory compatibility.
