Cry Havoc Takedown Kit (QRB Barrel Kit)

Cry Havoc Tactical takes their QRB (Quick Release Barrel) Upper Receiver Takedown Kit and scales it up for the big guns!
Designed for your AR 308 or 6.5 Creedmoor the QRB allows you to quickly detach the barrel giving you the ability to store or carry your rifle in a much-reduced profile and then when needed quickly reassemble the rifle while holding within 1 MOA.

Each Cry Havoc Takedown Kit contains complete instructions and all parts to convert your rifle or without drilling or any permanent modifications. Although they recommend installation be done by a Gunsmith, if you can install a barrel on an upper receiver, you can install this kit. Simple hand tools, an Armour’s wrench, and receiver block/vise are all that are needed. Returning your rifle or pistol back to stock is as easy as the installation.

The QRB main body is Hard Anodized Aluminum and the Stainless-Steel hooks, levers, star nut, and gas extension are finished in Black Nitride for maximum durability.

Available from Brownells

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.

The Tiger Stripe pattern is laser etched into the finish giving it a unique and comfortable texture.

Aero Precision M5 Stripped Lower Receiver APAR308003C

The Aero Precision M5 Stripped Lower is my go-to lower when folks ask for recommendations as well as for my builds. I like Aero Precision as a company, and their hardware is top-notch. The Aero .308 stripped lowers are about as vanilla as you can get, and to me, that’s a good thing. The lowers are DPMS platform and work best with Magpul 308 AR magazines. The only potential “gotcha” with the Aero M5 lowers is they require the Aero Precision M5 Extended Magazine Catch Button SKU# APRH101268C , which is about $5. For the life of me, I don’t understand why they aren’t included with the lowers.
