Paired with a pistol-length gas system, it provides optimal cycling and smooth operation. The pistol-length gas tube is perfect for compact AR-15 builds, reducing recoil and improving firearm control.

• Premium MLOK Handguards: The 12" free-floating carbine-length MLOK handguard is made from aircraft-quality aluminum and coated with black hardcoat anodizing for a rugged finish.
