Midwest Industries G4 Free Float AR-15 Handguard - M-LOK - 10.5"

The Midwest Industries G4 is a free float AR-15 handguard designed for shooters who want maximum M-LOK space without adding bulk. Its free float design keeps the rail off the barrel so nothing mounted on it can shift point of impact, while seven sides of M-LOK give you room to run lights, foregrips, and other accessories anywhere you need them.

Features:

• 6061 aluminum, Type III hard coat anodized
• Seven sides of M-LOK
• Continuous MIL-STD 1913 Picatinny top rail
• Five integral anti-rotation QD sling sockets
• Patented 4140 heat-treated torque plate and barrel nut
• Includes 5-slot polymer M-LOK rail
• Barrel nut and wrench included
• Fully dehorned and deburred
• Made in the U.S.A.

At 10.5" long and 8.8 ounces installed, this G4 handguard keeps a super slim 1.5" outside / 1.3" inside diameter. It's compact enough for a close-quarters carbine build without crowding out space for a light or foregrip.

Installation is straightforward: the handguard slides over the included 4140 heat-treated barrel nut and torque plate with no timing required, and anti-rotation tabs keep it locked against the receiver under recoil. It works with standard forged upper receivers, but not gas-piston AR systems, and billet-upper owners should confirm fit with their manufacturer first.

Midwest Industries builds handguards, rails, and iron sights for popular rifle platforms including the AR-15, AR-10, SIG MCX, and AK-47, backed by a lifetime warranty on every handguard they sell.
