ICON DEFENSE 308 DRIVE LOCK HAND GUARDS

Icon Defense has designed and developed the most rigid and robust hand-guard attachment system in the world! Our revolutionary, patent pending design uses three independent wedges that interface with the angular grooves in our proprietary barrel nut. This system clamps the rail onto the barrel nut with extreme force and precision, while also driving the hand guard rearward towards the upper receiver. The Drive Lock system provides the least amount of barrel-to-handguard flex while making it virtually impossible to slide forward off the barrel nut, ensuring your zero is maintained in the most abusive environments. When you’re looking for the most rigid and precise hand guard locking system available, the DRIVE LOCK hand guard locking system is your solution.

Icon Defense precision machined billet uppers are CNC machined from solid billet 7075-T6 aluminum, resulting in extremely tight tolerances and barrel extensions that are thermally fit to the upper receiver for superior accuracy. Receivers are finished with Mil-Spec Type 3 hard coat anodizing.
