6.5 Creedmoor

The 6.5 Creedmoor is a top choice for precision rifle competitors and hunters looking for the optimum AR-based extended-range cartridge. It makes ultra-long-range shooting an easy proposition and offers similar long-range trajectories to a .300 Winchester Magnum with less felt recoil than a comparable .308 rifle. The high ballistic coefficient bullets loaded in the 6.5 caliber make this downrange performance possible because they have less wind drift and more retained energy than a comparable .30 caliber bullet at 1000 yards. When seeking the best extended-range shooting or hunting performance in an AR platform rifle, the 6.5 Creedmoor is the logical choice. With a wide variety of quality factory ammunition available and .308 AR magazine and receiver compatibility, the 6.5 Creedmoor is in a performance class by itself.

Wilson Combat Super Sniper Profile Barrels

There are times when extreme accuracy and rapid follow-up shots are the most important criteria when selecting a rifle. Those were the primary objectives of the engineers at Wilson Combat® when they designed the Super Sniper– and the result far exceeded our expectations. It has a long, heavy-weight, stainless steel premium match-grade barrel– optimized for accuracy with the longer, heavier bullets frequently used for longer-range shooting. The Super Sniper is engineered, designed, and built to deliver unmatched accuracy, and it does in an almost unbelievable fashion.

Wilson Combat AR Barrel Service Policy

Because of the nature of the AR parts business and varying pressures of commercially available ammunition, Wilson Combat cannot guarantee function in customer-built AR rifles. We recommend a competent rifle-smith install all components.

If you assemble a firearm with Wilson Combat components and it fails to function, you first need to check the fit of the barrel to the gas block and the overall condition of your rifle’s gas system/bolt carrier group to ensure your system isn’t leaking gas. As buffers and springs play a role in overall reliability, the use of an aftermarket-style buffer system is not recommended. When using an adjustable gas block, reliability is best achieved at the fully open setting without any gas port restriction.

Wilson Combat will not troubleshoot customer-built firearms/uppers.

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.

After turning down the barrel, BSF Barrels jacket a 416R Stainless steel match barrel in a roll-wrapped carbon fiber sleeve and load it under tension.  BSF Barrels use this jacketing method rather than wrapping the barrel in carbon fiber because this method of wrapping has been proven to trap heat and cause delamination.

 The carbon fiber used is specially designed to move at the same expansion rate as 416R stainless steel. BSF Barrels drill holes into the carbon fiber allowing air to move around the barrel and vent heat quicker without any delamination issues.  Using the Carbon Fiber this way keeps the rifling straighter the warmer the barrel gets because it’s under tension. This allows us to maintain superior stiffness and strength while keeping the barrel extremely lightweight.

6.5 Creedmoor AR Barrels

Converting your large frame AR to shoot 6.5 Creedmoor is a simple barrel change. Whether replacing a .308 barrel or building a 6.5 Creedmoor AR from parts it is advisable to use a new bolt and of course verify proper headspace. Never use a bolt on different barrels. Many barrel manufacturers can provide a matching bolt.

It’s important to note that 6.5 Creedmoor is a relative new comer on the AR scene. A good knowledge of firearm function is imperative. Some builds and upgrades might require tweaking of the gun to function consistently and accurately. We recommend using and adjustable gas block when possible.

Add Proof Research to the list of 308AR barrel and rifle manufacturers to implement a non standard gas length on their 6.5 creedmoor barrels. Some companies refer to this new length as +2 (plus 2 inches). Proof Research designates their new gas length as “CAMGAS”. Moving the gas ports 2 inches closer to the muzzle adds a bit of dwell to the pressure curve. Basically it tames the action resulting smoother cycling and function. Check availability.

Proof research recommends the JP high pressure bolt. JP uses the high pressure bolt in their +2 rifles. Obviously a +2 gas tube is also required.

These long range specific barrels provide the ultimate in accuracy and will maintain their performance in the harshest of conditions.

The PROOF Research AR 308 PR-10 barrel uses the company’s innovative CamGas system, which works to reduce the speed of the bolt carrier and improve overall function and reliability of 6.5 Creedmoor semi-auto rifles.

Provide shooters with enhanced accuracy on par with match-grade guns
Better cooling properties provide improved barrel life

The PROOF Research AR 308 PR-10 barrel is cut rifled from double stressed relived 416R stainless steel and features a threaded muzzle with a 5/8×24 TPI thread pitch for the addition of muzzle accessories.

PROOF RESEARCH CAMGAS GAS SYSTEM

With the release of its new patent-pending Caliber Matched Gas System (CAMGAS) barrels, PROOF Research has eliminated the issues traditionally associated with building 6.5mm and .260 rifles on 308 AR AR-10 platforms. Until now, AR-variant shooters looking for ballistic advantages from either of these calibers were faced with excessive bore pressures that necessitated makeshift solutions such as clipping buffer springs, adjusting buffer weights, and/or relying on adjustable gas blocks, to keep their rifles functioning properly.

PROOF’s R&D team has solved the overpressure issue with gas systems tuned specifically to the cartridge/barrel-length combination. “By moving the gas port, the pressure in the bore is given time to reduce to that comparable of a .308 Winchester with a rifle-length gas system, which is what the 308 AR AR-10 system was designed around,” said Greg Hamilton, PROOF’s research-and-development weapons specialist who’s also a 3-Gun and PRS competitive shooter. “The recoil impulse is noticeably smoother, which helps keep you on target while taking advantage of a more efficient projectile. Case extraction is also easier, with less case-head smearing, so the brass is in much better condition for reloading.”

In recent years, 6.5mm Creedmoor and .260 Remington have become increasingly popular in long-range shooting competitions. The .260 in particular represents an outstanding caliber for a military counter-sniper role—out to roughly 1,000 meters—in smaller- to mid-sized weapon systems. It offers exceptional accuracy and superior ballistics over the ubiquitous .308 while dishing out substantially less recoil and enough energy to make it a legitimate contender for military and law enforcement applications.

“I’ve been using prototype CAMGAS barrels, in both .260 and 6.5 Creedmoor, in competition for almost a year with excellent results,” Hamilton explained. “Both rifles ran flawlessly through high-round, fast-cadence stages, firing hundreds of rounds with 100 percent reliability and zero maintenance or cleaning. From recoil to reliability, every aspect of performance was improved compared to the typical un-tuned barrel.”

PROOF Research currently offers Caliber Matched Gas System barrels chambered for 6.5mm Creedmoor and .260 Remington in three separate lengths: 20, 22, and 24 inches. Every CAMGAS barrel comes standard with an easy to install custom-length gas tube.
