Arisaka MCX Spear LT Zero Retention Handguard Clamp

The Arisaka Defense MCX Spear LT Zero Retention Clamp is a handguard-stabilizing component designed to reduce movement between the SIG MCX Spear LT handguard and upper receiver. Its purpose is to provide a more rigid relationship for accessories such as lasers or front sights that are mounted on the handguard and depend on the handguard returning to the same position. This black aluminum version is intended for the standard Spear LT handguard configuration covered by Arisaka.

The clamp system uses an internal U-bracket and exterior clamp pieces to secure the handguard more firmly to the extended upper receiver. It does not replace the handguard and does not contact the barrel or gas system, so the product should be viewed as a reinforcement component rather than a new rail assembly. Compatibility is model-specific, which makes it important to verify the firearm and handguard version before installation.

This clamp is most relevant when handguard-mounted aiming equipment makes repeatable handguard position important to the overall setup. Installation and removal should follow the manufacturer procedure because the clamp must be removed before the handguard itself is taken off the rifle.
