The Diamondback 308M135M50B10 OEM Replacement 308 Win 13.50″ Mid-Length Black Nitride 4150 Chrome Moly Vanadium Steel Made a Bold First Impression
As an experienced outdoor and tactical gear specialist, I’ve seen my fair share of AR-10 components. The Diamondback 308M135M50B10 OEM Replacement 308 Win 13.50″ Mid-Length Black Nitride 4150 Chrome Moly Vanadium Steel barrel immediately piqued my interest with its unique 13.5-inch length and promises of reliability at an accessible price point.
My latest AR-10 build demanded a barrel that was both maneuverable and capable of delivering solid performance. I was after a balance, something that could be effective in closer-quarters scenarios but still have enough gas system to avoid being overly harsh on the action.
Upon unboxing, the barrel presented a clean, dark aesthetic thanks to the black nitride finish. The 4150 Chrome Moly Vanadium steel gave it a reassuring heft, promising durability, and the threads were clean and properly cut.
Compared to other barrels in my collection, particularly a heavier 16-inch stainless steel offering and a lighter 12.5-inch pistol-length barrel, this Diamondback barrel seemed to strike a sweet spot. I wanted something shorter than the standard 16″, while also moving away from the sometimes unreliable gas system of very short barrels.
My initial excitement stemmed from the potential this barrel held for creating a compact and reliable AR-10 platform. I was eager to see how it performed in live fire and whether it lived up to the Diamondback name.
Real-World Testing: Putting Diamondback 308M135M50B10 OEM Replacement 308 Win 13.50″ Mid-Length Black Nitride 4150 Chrome Moly Vanadium Steel to the Test
First Use Experience
My initial testing took place at a local shooting range, focusing on accuracy and reliability with various .308 Winchester loads. I ran everything from cheap surplus ammo to match-grade rounds through the Diamondback 308M135M50B10.
The barrel performed admirably, cycling reliably with all ammunition tested, with only a very minor tweaking of the buffer weight needed for optimal function with the lighter loads. While I didn’t encounter rain during my first outing, the range was slightly dusty, and the nitride finish seemed to resist collecting debris effectively.
The 13.5-inch length required a slight adjustment to my shooting stance and cheek weld compared to my longer barreled AR-10s, but the transition was smooth. I encountered no immediate issues, and the barrel’s initial performance was promising.
Extended Use & Reliability
After several months and hundreds of rounds, the Diamondback barrel has proven to be remarkably consistent. I’ve used it in various shooting scenarios, including tactical drills and longer-range target practice.
Despite frequent use, the black nitride finish shows minimal wear and tear, even with aggressive cleaning. Cleaning has been straightforward, with carbon fouling easily removed from the bore and chamber.
The Diamondback barrel has consistently outperformed some of my other, more expensive barrels in terms of sheer reliability, especially with less-than-ideal ammunition. The mid-length gas system proves to be a wise choice, offering a balance between a smooth recoil impulse and consistent cycling.
