Arisaka Defense ZRC MCX MI Suppressor Clamp for MCX Virtus & Spear LT

The Patent Pending Arisaka Zero Retention Clamp (ZRC) greatly reduces zero shift for lasers and iron sights mounted on the handguard of the MCX Virtus and Spear LT.

Designed for:

• MCX Virtus chambered in 5.56 and 300BLK
• Spear LT chambered in 5.56, 7.62x39, and 300BLK
• (The Rattler is not currently supported.)

How it works:

• The ZRC uses exterior clamps that thread into a special U-bracket.
• The U-bracket engages the extended upper receiver underneath the handguard, securing it across two axes.
• The U-bracket does not touch the barrel or gas system, preserving a free-floated barrel.
• Contoured clamps help minimize interference with the user’s hands while gripping the handguard.
