Description
The Ultimate Handguard Locking System – SIONICS RM LOCK
SIONICS has engineered the most rigid, robust, and reliable handguard attachment system on the market. Our revolutionary, patent-pending RM LOCK 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? Not Here. The RM LOCK system virtually eliminates barrel-to-handguard flex, ensuring your zero stays rock-solid, even in the most punishing conditions.
- No Slippage. No Failures. Designed for absolute durability, this system won’t slide forward under stress, impact, or extreme use.
- Hand-Finished Excellence. Each part is meticulously crafted and finished by hand to eliminate imperfections and ensure superior fit and function.
Proudly Built in Tumwater, USA
When you demand the toughest, most precise handguard locking system available, SIONICS RM LOCK delivers.
