Sig Sauer Tread Forward Grip Kit – 13 inch M-LOK, Black

The Sig Sauer Tread forward grip kit (brand part no. KIT-TRD-GRIP-FORWARD-BLK) is the factory replacement kit for the M400 Tread rifle series, sized for 13-inch M-LOK handguards and finished in black. Rather than a single accessory, the kit bundles a vertical foregrip, barricade stop, handstop, finger stop, and both a short and long M-LOK rail panel, giving shooters every forward-grip configuration option in one order. Because it’s built around the M-LOK standard rather than a proprietary mount, the kit works on any M-LOK-compatible handguard, not just genuine Sig Tread rifles. At just 0.395 lb shipped, it adds real versatility without meaningfully adding weight to the front of the rifle.
