The 12 inch KeyMod Handguard by Barska is a free floating handguard that utilizes the KeyMod accessory attachment system for increased weight savings, modularity, and ergonomics. These KeyMod slots provide almost limitless combination of mounting points without the extra weight associated with similarly sized Picatinny rails. The KeyMod Slots are located at the 3, 6, and 9 o'clock positions, and the Picatinny top rail has been designed to fit seamlessly with a mil-spec upper receiver. The 12 inch KeyMod Handguard is ideal for use with low-profile gas blocks on carbine, mid, or rifle-length gas systems.
