Sig Sauer M400 Tread 15" M-LOK Free Float Handguard - Black

The Sig Sauer M400 Tread 15" M-LOK Free Float Handguard is a factory replacement handguard built specifically for the Sig Sauer M400 TREAD AR-platform rifle. Machined from aluminum with a black anodized finish, this 15" free-float handguard provides a rigid mounting platform while shedding weight through integrated lightening cuts.

M-LOK accessory mounting slots run along the sides and bottom for straightforward attachment of lights, lasers, grips, and other M-LOK compatible accessories. The two-screw mounting design allows direct swap-out from the factory handguard on TREAD-series rifles with no gunsmithing required.

As a genuine Sig Sauer OEM part, this handguard maintains correct fit and alignment with the M400 TREAD's free-float barrel system. The anodized black finish matches Sig Sauer's standard color profile and provides corrosion resistance for long-term field durability.
