YOUR AR-15 JUST GOT AN UPGRADE.

Nothing says “flexible firepower” better than the ability to change out your caliber at will. Our patented War Lock™ system allows you to break down your weapon, change the bolt and barrel, then fire downrange with your new caliber – all with the same AR-15 upper and lower.

WHY WAR LOCK?

Our multi-caliber system is the best product on the market, developed with mathematical precision and extensive testing.

FIRE MORE THAN 90 CALIBERS.

The War Lock™ system expands your AR-15 caliber range from just the .223/.556 standard, to sizes from the .17 Remington all the way to .50 Beowulf rounds.
