The brand new SIONICS Handguard  – SIONICS S-15 RM-LOK

This patent-pending innovation employs three independent CAMs that precisely interlock with the titanium barrel nut’s proprietary RM grooves. The result? Unparalleled rigidity and reliability. RM-LOK delivers an exceptionally strong clamping force, effectively locking the handguard to the barrel nut while simultaneously eliminating any play by driving it firmly against the upper receiver. Experience the pinnacle of handguard stability.

Description

The Ultimate Handguard Locking System – SIONICS RM-LOK

SIONICS has engineered the most rigid, robust, and reliable handguard attachment system on the market. Our revolutionary, patent-pending RM-LOK system utilizes three independent CAMS that precisely engage with the Rotating Mechanism (RM) grooves in our proprietary barrel nut. This system creates an ultra-secure clamp, locking the rail onto the barrel nut with extreme force and precision, while simultaneously driving the handguard rearward toward the upper receiver.

Unmatched Stability. Uncompromised Performance.
  • Zero Shift. The RM-LOK system virtually eliminates barrel-to-handguard flex, ensuring your zero stays rock-solid, even in the most punishing conditions. Whether you are loading into a bipod, tripod, or barricade, rest assured you will see ZERO POI shift.
  • No Slippage. No Failures. Designed for absolute durability, this system won’t slide forward under stress, impact, or extreme use.
  • Titanium Barrel nut – Our Titanium barrel nuts offer a significant performance upgrade. Their superior strength and rigidity, coupled with enhanced heat dissipation compared to aluminum, provide a more robust and thermally efficient solution. Plus, you’ll benefit from a noticeable weight reduction.
  • Steel QD Inserts – Anti-Rotational steel QD inserts insure long lasting engagement with your sling mounting solutions.
  • Unmatched Anti-Rotation – Engineered for maximum stability, the extrusion features integrated anti-rotation tabs and a supplemental dowel pin interface for compatible upper receivers, eliminating rotational movement.
  • Simple barrel nut tooling – We engineered the barrel nut for compatibility with standard castle nut wrenches, eliminating the need for costly, proprietary tools.
