Overview

Designed for the MCX Virtus in 5.56mm, this clamp is intended to help reduce zero shift for lasers and iron sights mounted on the handguard. It is compatible with the Sig Sauer OEM slim handguard and the Midwest Industries standard M-Lok handguard, making it a focused fit for those specific setups. Arisaka also notes a newer combined 5.56/300BLK version with a tighter lockup, so this model is best considered when matching the exact configuration listed here. For hunters and shooters who rely on handguard-mounted aiming devices, it offers a purpose-built retention solution without unnecessary complexity.

  • The product description recommends the newer combined 5.56/300BLK ZRC instead, noting that it uses an internal U-bracket with two clamps for a tighter lockup and broader handguard compatibility.
  • It is designed to reduce zero shift for lasers and iron sights mounted on the handguard, so it is a mounting accessory rather than a general-purpose handguard upgrade.
  • A different version is required for other setups, so fitment should be checked carefully before purchase.
