Let’s Dive into Guntec USA AR-10 Chrome Car Stock Spring, .308 Cal
The Guntec USA AR-10 Chrome Car Stock Spring, .308 Cal promises smoother cycling and reduced noise for your AR-10 carbine build. It’s a seemingly small component, but the recoil spring plays a crucial role in the rifle’s overall function.
I’ve been building and maintaining AR platforms for over a decade, both AR-15s and AR-10s, for competitive shooting and tactical applications. When a client requested an AR-10 build chambered in .308, I immediately began sourcing high-quality components that would ensure reliability and performance. One key area often overlooked is the buffer system, and more specifically, the buffer spring.
Upon unboxing, the Guntec USA spring immediately stood out with its shiny chrome finish. It felt noticeably smoother than standard phosphate-coated springs, and the build quality appeared solid, suggesting a well-made product.
Several other AR-10 buffer springs were available, including options from Brownells and Sprinco. I chose the Guntec USA AR-10 Chrome Car Stock Spring, .308 Cal due to the appealing combination of the chrome/Teflon coating’s promise of smoother operation and the attractive price point. This product seemed to offer a good balance of features and value.
My initial impression was positive. The smooth finish and the promise of reduced noise were exciting, and I was eager to see if it would live up to the claims during testing.
