It dipped to $251.74 at GritR Sports for a stretch in August 2026, well under its usual $300, so sales do come around.

Geissele Mk16 9.3 light
Reviewed on April 21, 2026Verified with Build

Geissele Mk16 9.3 inch handguard in black is lighter than I expected for the length. Stays comfortable across long range sessions. Free float aluminum body. The bolt up system clamps tight to upper. Premium short rail.
