SIG TREAD HANDGUARD 15″ MLOK BLK

This 15″ Tread M-LOK free float handguard features lightening cuts and is a two screw replacement for the Sig Tread rifle series. While compatible with other AR-15 pattern rifles, it does not include the barrel nut which would be required to install the handguard on a rifle other than the Sig M400 Tread. Barrel nut is sold separately.
