QRB WORKS FOR ALL CALIBERS THAT OPERATE ON AR-15 UPPER RECEIVERS![]()
The QRB Kit can only be used on Barrels with a maximum outside diameter of 0.985in and Free Float Hand Guards with a maximum width of 2.0in.
For your AR-15 style rifle or pistol. Change calibers in seconds! The QRB allows you to remove the barrel of your rifle or pistol quickly. NO drilling or modifications needed!
Our QRB System is designed to work with Gas Impingement or Blow Back Weapons using Free Float Hand Guards 2in wide or less. The QRB has successfully been used on 223/556, 7.62x39, 22 Rimfire, 9mm, 40 Caliber, 45 Caliber, 300 Blackout, Bushmaster 450, 458 SOCOM and 50AE. If looking to use with a AR10 Style 308 or 6.5 Creedmoor, make sure to check out the 308 QRB tab! Our Patented Quick Release Barrel Kit for the AR-15/M4 lets YOUR rifle or pistol easily takedown into a very small package without drilling or other modifications to install. As an example below, a 16in Barreled Carbine with an overall length of 33.5in now becomes two 17.5in pieces. Try that with just removing the upper with pushing the pins - you'll end up with a 16in piece and a HUGE 25+in piece - Forget fitting that in a small pack or briefcase without sticking out. THE QRB is for those who don't want to leave their rifle at home.
