**** Our QRB System is designed to work with Gas Impingement or Blow Back Weapons using Free Float Hand Guards 2" 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 16" Barreled Carbine with an overall length of 33.5" now becomes two 17.5" pieces. Try that with just removing the upper with pushing the pins - you'll end up with a 16" piece and a HUGE 25+" 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.
