Let’s Dive into Criterion Barrels AR-10 Mid Length Nitrided Gas System Barrel
The Criterion Barrels AR-10 Mid Length Nitrided Gas System Barrel promises enhanced accuracy and reliability for your .308 build. Criterion Barrels has a reputation for quality, and this barrel aims to deliver on that promise. It’s designed for both 7.62×51 NATO and .308 Winchester ammunition, offering versatility in a durable platform.
For years, I’ve struggled to find an AR-10 barrel that consistently delivered sub-MOA accuracy without costing a fortune. My older .308 build had a tendency to throw shots, especially after the barrel heated up. I needed something dependable for both hunting and longer-range target shooting, a barrel that wouldn’t break the bank but still offered exceptional performance.
The Criterion Barrel’s hybrid contour and nitrided finish immediately caught my eye when I unboxed it. The finish was flawless, and the weight felt right – not too heavy to carry, but substantial enough to suggest a quality build. The hand-lapped bore also seemed like a good sign, showing Criterion’s attention to detail.
I considered barrels from Faxon and Ballistic Advantage, both solid options in the AR-10 market. However, Criterion’s reputation for accuracy and the mid-length gas system tipped the scales for me, figuring a slightly longer gas system would make it a softer shooter. I also was intrigued by the idea of a hand-lapped bore.
My first impression was definitely excitement. It felt like a serious upgrade, a step towards the consistent accuracy I’d been chasing.
Real-World Testing: Putting Criterion Barrels AR-10 Mid Length Nitrided Gas System Barrel to the Test
First Use Experience
I first tested the Criterion Barrel at my local outdoor range, a spot known for its challenging wind conditions. The temperature was around 60 degrees Fahrenheit, with a slight drizzle. The range offers targets out to 600 yards, perfect for stretching the legs of a .308.
The barrel performed remarkably well, even in the less-than-ideal conditions. It cycled flawlessly with both Federal Gold Medal Match .308 and some surplus 7.62×51 I had lying around. The mid-length gas system felt smooth, recoil was manageable, and the rifle ran without a single hiccup.
The barrel proved easy to use, with the .750 gas block aligning perfectly. Installation was straightforward, and I had the barrel installed and ready to go in under an hour. After the first few shots, I was very impressed.
Extended Use & Reliability
After several months of use, the Criterion Barrel has proven to be exceptionally reliable. I’ve put several hundred rounds through it, from cheap plinking ammo to high-end match loads. It consistently maintains sub-MOA accuracy with match ammo.
So far, there are no signs of significant wear and tear. The nitrided finish has held up well against scratches and corrosion. Cleaning has been easy, thanks to the smooth, hand-lapped bore.
The Criterion Barrel definitely outperforms my previous barrel. The accuracy is noticeably better, and it’s much more consistent, even after extended periods of shooting. It’s a significant improvement in my AR-10’s overall performance.
