CMMG 6.5 Creedmoor Non-Threaded Barrel Review

First Impressions of CMMG 6.5 Creedmoor Non-Threaded Barrel

The CMMG 6.5 Creedmoor Non-Threaded Barrel promises a compelling blend of accuracy and regulatory compliance. CMMG is a well-respected name in the AR-15 parts market, known for quality and innovation. This particular barrel caught my attention because I needed a 6.5 Creedmoor barrel for a precision build, but the absence of threading was crucial to remain compliant with local laws.

I’ve been wanting to explore the long-range capabilities of the 6.5 Creedmoor cartridge for some time, particularly for ethical hunting at extended distances. However, I reside in a state with restrictions on threaded barrels for certain firearms. The CMMG 6.5 Creedmoor Non-Threaded Barrel presented the perfect solution: a high-quality barrel chambered in a fantastic cartridge, without the legal headaches.

Upon receiving the barrel, the first thing I noticed was the solid feel and clean finish. The Salt Bath Nitride (SBN) finish looked even and robust. The medium-taper Empire Profile appeared well-machined and ready for action.

Compared to other barrels I’ve used, like those from Ballistic Advantage and Criterion, the CMMG barrel strikes a balance between cost and perceived quality. While some higher-end barrels boast hand-lapping and more exotic materials, the CMMG seemed to offer a practical, accurate option without breaking the bank. I chose the CMMG over a similar offering from Bear Creek Arsenal because of CMMG’s reputation for better quality control and more consistent accuracy. My first impression was positive, and I was eager to get it installed and tested at the range.

Real-World Testing: Putting CMMG 6.5 Creedmoor Non-Threaded Barrel to the Test

First Use Experience

I first tested the CMMG 6.5 Creedmoor Non-Threaded Barrel at my local shooting range, a 200-yard outdoor facility. The weather was slightly overcast with a mild breeze, offering decent conditions for initial accuracy testing. I paired the barrel with a quality bolt carrier group, a precision-tuned trigger, and a high-magnification scope.

The initial groups at 100 yards were promising, hovering around 1 MOA with factory ammunition. I did experience a few initial failures to feed, which I attributed to the new barrel breaking in. After about 20 rounds, the feeding issues disappeared entirely.

Extended Use & Reliability

After several months of use, the CMMG 6.5 Creedmoor Non-Threaded Barrel has proven to be reliable and consistent. I’ve put approximately 500 rounds through it, including a mix of factory ammunition and handloads. The accuracy has remained consistent, with most loads delivering sub-MOA performance.

There are no noticeable signs of wear and tear on the barrel. The SBN finish has held up exceptionally well, resisting scratches and corrosion. Cleaning the barrel is straightforward; standard bore solvents and brushes remove fouling effectively. Compared to a previous stainless steel barrel I owned, this CMMG barrel seems to clean up much easier. It has definitely exceeded my expectations for a mid-priced barrel.

Breaking Down the Features of CMMG 6.5 Creedmoor Non-Threaded Barrel

Specifications

• Caliber: 6.5 Creedmoor. This caliber is known for its excellent ballistic coefficient and long-range accuracy.

• Barrel Length: 20 inches. The 20-inch length helps maximize the velocity and ballistic performance of the 6.5 Creedmoor cartridge.

• Barrel Material: 4140 Chrome Moly Vanadium. This material is known for its strength and ability to withstand high temperatures.

• Finish: Salt Bath Nitride (SBN). SBN provides excellent corrosion resistance and surface hardness.

• Muzzle: Non-Threaded with Recessed Target Crown. The unthreaded design ensures regulatory compliance in certain states, and the recessed target crown promotes consistent bullet release for improved accuracy.

• Profile: Medium Taper Empire Profile. The medium taper strikes a balance between weight and rigidity, contributing to both accuracy and manageable handling.

Performance & Functionality

The CMMG 6.5 Creedmoor Non-Threaded Barrel performs admirably, delivering consistent accuracy and reliable function. Its ability to consistently produce sub-MOA groups speaks to its quality and precision. There are no significant weaknesses, though some may prefer a threaded muzzle for ease of adding muzzle devices (this is, of course, not possible with this model). It definitely meets my expectations for accuracy and reliability in a 6.5 Creedmoor barrel.

Design & Ergonomics

The barrel’s design is functional and aesthetically pleasing. The 416 stainless steel construction ensures durability. The weight is manageable for a 20-inch barrel, not overly heavy but substantial enough to contribute to stability. The barrel has a very user friendly design.

Durability & Maintenance

With proper care, the CMMG 6.5 Creedmoor Non-Threaded Barrel should last for thousands of rounds. The SBN finish significantly enhances its resistance to corrosion and wear. Maintenance is simple, requiring only regular cleaning with standard bore cleaning supplies.

Accessories and Customization Options

As a barrel, it primarily interfaces with other AR-15 components. It is compatible with standard AR-15 uppers and gas systems. Being non-threaded, the primary customization limitation is the inability to easily attach muzzle devices. It accepts standard AR-15 gas blocks.
