M4 handguards, cool tunnel.  Blackthorne's EXCLUSIVE "Cool Tunnel" technology M4 hand guards.  We use a proprietary hight temp polymer and patented "Cool Tunnel" design.  Two linear ribs on the inside of the handguard direct the heat generated from firing out the vent holes  instead of trapping it in.  The inside of the handguards are coated with an aluminized heat reflective coating which further increases cooling.  For barrels up to 1.020" diameter.  From the outside they are indistinguishable from standard M4 handguards.
