Once the QRB Kit is installed, it is amazingly quick to assemble your rifle or pistol without the worry of damaging your gas tube. The operator would simply lock the bolt back, insert the barrel extension into the receiver, rotate the barrel until the alignment pin enters the alignment hole, and then seat the barrel in place. Next, hook the two clips on the receiver plate and engage the levers to the closed position, never taking your hand off the pistol grip. Nothing to depress! Just drop the bolt and you are ready to fire… All in less than 6 seconds!
To remove the barrel assembly for storage, first, remove the magazine, lock the bolt back, check for an empty chamber, pull levers away from the handguard, remove hooks from the receiver plate and pull the barrel away from the receiver. Just that simple. No barrel rattling around in the handguard or gloves needed! Make sure to check out the videos in the Media Tab to see these steps happen in real-time. You will be amazed.
- The QRB Kit is only compatible with Free Float Hand Guards 2.2″ wide or less and will add 1.7″ to the length of the Hand Guard.
- Purchase the correct kit by selecting the proper length gas tube to your barrels gas system length.
