Haga Defense PS90 Front Handguard

The Haga Defense PS90 front handguard adds an M-LOK accessory rail to the standard PS90 forend without requiring a full chassis conversion. The handguard mounts to the factory PS90 receiver and replaces the factory polymer forend with a CNC-machined aluminum unit that exposes M-LOK slots for lights, lasers, and forward sling mounts.

Haga produces two variants. The standard at $175.49 / 4.6 oz fits any PS90 with the factory barrel and shroud. The wide suppressor-compatible variant at $244.68 / 3.7 oz is sized to clear common 5.7x28 suppressor profiles, which matters once a Mask HD or Flow 22 Ti is mounted up front. Both variants fit both old (~31mm) and new (~33mm) PS90 receiver widths automatically.

For owners who want modular accessory mounting without the cost and complexity of the Strike SMC-90 chassis, this is the right answer. Pair with the Haga PS90 cheek riser and matching optic mount for a coordinated upgrade package.
