Midwest Industries G4 M-LOK - Free Float Handguard - 13.375"

The Midwest Industries 13.375-inch G4 M-LOK free float handguard provides seven sides of M-LOK coverage in the G4's slim 1.5-inch outside diameter format — extending the compact grip profile of the G4 platform to a longer length suited for 16-inch barrel builds that benefit from full handguard coverage. Built for AR-15 platforms, this free float handguard is machined from 6061 aluminum with a hard coat anodized finish.

The Midwest Industries G4 is a 13.375-inch free float M-LOK AR-15 handguard machined from 6061 aluminum with a hard coat anodized finish, measuring 1.5 inches in outside diameter and 1.3 inches in inside diameter, with seven sides of M-LOK compatibility.

The slim 1.5-inch outside diameter is consistent across the G4 lineup — the same compact grip profile that the 10.5-inch model provides, now extended to 13.375 inches for builds where a longer handguard with the same slim profile is the requirement. Seven sides of M-LOK across the 13.375-inch handguard body give comprehensive accessory mounting coverage at all quadrants and diagonals, providing full placement flexibility for lights, lasers, grips, bipods, and slings. 6061 aluminum with hard coat anodize provides the structural integrity and surface durability that the free-float installation demands.

Compatible with AR-15 platforms. 13.375" length. 1.5" OD. 1.3" ID. Seven sides M-LOK.
