MEET THE WAR LOCK

  • The War Lock replaces the barrel nut on an AR-15.
  • Once installed, you can remove the entire barrel assembly without tools.
  • By changing barrels, magazines, and sometimes the bolt, your rifle can then shoot over 90 calibers.
  • Yes, it’s that simple.

  • The War Lock is designed to work with the widest variety of AR-15 parts possible.
  • Everyone hates proprietary systems, and we are no different.
  • Shop around for the best prices on barrels, gas blocks, or use what you already have.
  • The AR-15 is a very modular platform, and our goal was to create an upgrade that plays well with others.

  • From the very beginning, we designed the War Lock to be a Multiple Caliber System. It’s also a “takedown” system as a happy side benefit.
  • We proudly make the War Lock in America, using high quality steel. We believe our products should be an investment that you can hand down to your family. Call us old fashioned.
  • We’ve done the math. The designing, engineering and testing was done specifically to ensure that you have the most options, with an easy to use system. American ingenuity is back for good.
