Sig Sauer M400 TREAD Ambidextrous Charging Handle Black KIT-TRD-CHARGING-HANDLE UPC 798681598823
Product Description
The Sig Sauer M400 TREAD Ambidextrous Charging Handle (KIT-TRD-CHARGING-HANDLE) is an ergonomic, high-performance upgrade designed for Sig Sauer M400 TREAD rifles and all standard Mil-Spec AR-15 upper receivers. Purpose-built to enhance weapon manipulation under high-stress conditions, this dual-latch design provides effortless, mirrored operation for both left- and right-handed shooters.
Precision CNC-machined from high-strength 7075-T6 aircraft-grade aluminum and finished in a hardcoat anodized matte black coating, the KIT-TRD-CHARGING-HANDLE is engineered to withstand violent bolt cycling, harsh thermal buildup, and hard field use. The dual oversized latches feature deep, textured aggressive serrations that provide positive traction and smooth one-handed charging, even when wearing heavy tactical gloves or clearing optics.
As a direct drop-in factory replacement component from Sig Sauer's official TREAD accessory line, this charging handle improves clearing drills, dynamic reloads, and optic clearance without requiring permanent gunsmithing or receiver modifications.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits Sig Sauer M400 TREAD, M400 series, and all standard Mil-Spec AR-15 / M4 upper receivers. (Not compatible with AR-10 / SIG716 large-frame platforms or non-standard proprietary side-charging uppers).
- Perform a complete firearm safety check: drop the magazine, lock the bolt rearward, and visually inspect the chamber to verify zero live rounds are present.
- Point the muzzle in a safe direction and allow the bolt carrier group to move forward to battery.
- Push out the rear takedown pin and pivot the upper receiver open from the lower receiver.
- Depress the charging handle latch, pull the factory charging handle backward halfway, and remove both the charging handle and bolt carrier group from the upper receiver.
- Apply a thin layer of quality gun oil or grease to the top and side rails of the Sig Sauer TREAD ambidextrous charging handle.
- Align the new charging handle key into the upper receiver track, insert the bolt carrier group, and push both assemblies forward into battery until the latch engages the receiver notch.
Key Features
- Dual-Latch Ambidextrous Controls: Identical oversized actuation latches on both sides allow seamless single-finger or palm-strike charging for left- and right-handed operators.
- 7075-T6 Billet Aluminum Construction: Machined from high-strength aircraft aluminum alloy to prevent latch flex, bending, or breakage under heavy leverage.
