The Midwest Industries SP Series 10.5-inch M-LOK handguard is a one-piece free float handguard sized to cover a suppressor on an AR-15 (Midwest Industries part no. MI-SP10M). Midwest Industries sells it under the Suppressor Series name, with an inside diameter that clears suppressors up to 1.55 inches. It is built from hard coat anodized 6061 aluminum, with M-LOK slots on seven sides and a MIL-STD 1913 top rail. A barrel nut and wrench are included, so the swap needs no extra parts.
