A free floating handguard mounts only to the upper receiver via its own barrel nut, never touching the barrel. This preserves barrel harmonics for better accuracy and improves heat dissipation. Typically M-LOK, KeyMod, or Picatinny for accessory mounting. Works with: AR-15/AR-10 upper receivers, dedicated barrel nut, compatible barrels, low-profile gas blocks, gas tubes (pistol/carbine/mid/rifle), and muzzle devices. Pairs with optics/iron sights, lights, grips, switches, and sling mounts on the rail. Ideal for precision and modern tactical builds.
