Luth-AR 308 Buffer Spring Review

Let’s Talk About Luth-AR 308 Buffer Spring

The Luth-AR 308 Buffer Spring is a seemingly simple component that plays a crucial role in the cycling and reliability of AR-10 platform rifles and some AR pistol builds. Manufactured by Luth-AR, a company known for its quality AR components, this spring is designed to absorb recoil energy and ensure proper feeding of ammunition. Its affordability and reputation for consistent performance made me curious to see if it lived up to the hype.

I was experiencing inconsistent cycling in my AR-10 build, sometimes failing to fully chamber rounds or having excessive recoil. I wanted a reliable, budget-friendly solution to try before investing in more expensive buffer systems. The Luth-AR 308 Buffer Spring seemed like a good starting point.

Upon receiving the spring, I was immediately struck by its simple, no-frills design. The tempered spring steel had a clean, silver finish and the coil tension felt firm and consistent. Compared to a generic buffer spring I had previously used, the Luth-AR offering felt noticeably more robust and better made. My initial impression was positive, hoping it was a simple, affordable fix.
