Let’s Talk About CMMG .350 Legend 16.1in Barrel Sub-Assm
The CMMG .350 Legend 16.1in Barrel Sub-Assm is a crucial component for anyone looking to build or upgrade their AR-15 platform to chamber the increasingly popular .350 Legend cartridge. Manufactured by CMMG, known for their quality AR parts, this barrel promises accuracy and durability. It’s designed as a drop-in solution for standard AR-15 uppers, which simplifies the building process.
I was seeking a reliable and accurate barrel to convert my existing AR-15 into a dedicated hunting rifle for deer season in states with straight-wall cartridge restrictions. The .350 Legend seemed ideal, offering sufficient power and range, so I needed a barrel I could trust.
Out of the box, the CMMG barrel felt solid and well-made. The nitride finish gave it a sleek, dark appearance and promised corrosion resistance. Its weight felt appropriate for a 16-inch barrel, not too heavy, but substantial enough to inspire confidence in its robustness.
I considered barrels from Ballistic Advantage and Aero Precision, both reputable manufacturers. However, I chose the CMMG due to its established reputation in the AR parts market and positive reviews I’d seen regarding their barrel accuracy.
My first impression was positive; the barrel exuded quality and I was eager to see how it performed on the range. I was definitely excited about the prospect of a dedicated deer hunting AR.
Real-World Testing: Putting CMMG .350 Legend 16.1in Barrel Sub-Assm to the Test
First Use Experience
I initially tested the CMMG .350 Legend 16.1in Barrel Sub-Assm at my local outdoor shooting range. The weather was clear, with a slight breeze, ideal conditions for sighting in a new barrel. I used a variety of factory .350 Legend ammunition from Winchester and Federal, ranging in bullet weight from 150 to 180 grains.
The barrel performed admirably, though it took some time to fine-tune the gas system. Cycling was initially inconsistent, but after adjusting the gas block, it ran reliably with all ammunition types I tested.
The initial groups at 100 yards were around 2 inches, which was acceptable, but I expected better. No major issues arose during the first outing, but the need for gas system adjustment was a minor inconvenience.
Extended Use & Reliability
After several months of consistent use, the CMMG barrel has proven to be quite durable. I’ve put several hundred rounds through it without any significant issues.
The nitride finish has held up well, showing no signs of rust or corrosion, despite exposure to varying weather conditions during hunting trips. Cleaning is straightforward; a standard bore brush and solvent make quick work of carbon buildup.
Compared to other AR barrels I’ve used in the past, the CMMG barrel holds its own in terms of accuracy and reliability. While it might not be a match-grade barrel, it is more than sufficient for hunting and recreational shooting purposes.
