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.
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.
