Sig Sauer M400 Tread 13" M-LOK Free Float Handguard Black

The Sig Sauer M-LOK Handguard is a factory-replacement 13" free-float handguard purpose-built for the Sig M400 Tread rifle. Machined from aluminum and finished in a durable black anodized coating, this handguard installs on the M400 Tread using the factory two-screw mounting system for a direct factory fit.

Continuous M-LOK accessory slots run along the handguard, giving you a modular platform for mounting lights, lasers, foregrips, bipods, and other M-LOK-compatible accessories. Lightening cuts are milled through the aluminum to keep overall weight at just 234.8 gr (0.52 lbs), helping the rifle balance well whether you are running it as a defensive carbine, duty gun, or recreational range rifle.

As a genuine Sig Sauer factory part, this handguard delivers an exact fit and finish. It is ideal for refreshing a worn M400 Tread, switching to a longer free-float platform, or replacing a damaged original. This listing is for the 13" M-LOK free-float handguard only.
