The Cry Havoc Tactical QRB (Quick Release Barrel) 1 Pin Upper Receiver Takedown Kit for AR-15 style rifles or pistols. Change calibers in seconds! The QRB allows you to remove the barrel of your rifle or pistol quickly. No drilling or modifications needed!

  • Fit your AR-15 Carbine or Pistol into a Backpack or Bugout Bag with ease. Perfect for discreet transport.
  • Assemble and Fire in seconds, even in low light. Able to KEEP strong hand on grip - Nothing to Depress or twist with strong hand.
  • Use gross motor skills to assemble due to two-piece gas system. No lining up tiny gas access hole with gas tube first!
  • Able to use a wide range of Free Float Hand Guards for the attachment of Back-up Iron Sights and accessories.
  • Super-fast barrel and upper cleaning.
  • The QRB can retain POA/POI as the barrel still ""head-spaces"" off the stock positions (our tests have shown accuracy retained to less than 1 MOA of original rifle setup!).
  • With the purchase of an additional Barrel Lock Plate, switching to a different barrel length or caliber, like the 300 Blackout, takes just seconds!
  • Proudly made in the USA
  • The QRB Kit can only be used on Barrels with a maximum outside diameter of 0.985"" and Free Float Hand Guards with a maximum width of 2.0"" Also the QRB will add 1.5"" to the length of your free-floating hand guard.

To purchase the proper kit simply selection the gas tube option that matches up with your barrels gas system length. A kit designed for pistol caliber AR’s that does not include a gas tube is available as well.
