The Midwest Industries G4M Tactical Handguard, 13.3 inches, M-LOK (brand part no. MIG4M13375) is a one-piece free-float handguard machined from 6061-T6 aluminum and finished in black hardcoat anodizing. It uses a 4140 heat-treated barrel nut and torque plate for a secure, durable mount, and a super-slim 1.5-inch outside diameter paired with a 10.3-inch inside diameter keeps the profile trim in hand. A continuous MIL-STD-1913 Picatinny top rail runs the full length for optics and accessories, while M-LOK slots around the rest of the handguard cover mounting needs everywhere else. Made 100% in the USA. For AR-15 builders who want a slim, full-length free-float handguard, this AR handguard is a one-piece upgrade.
