The Luth-AR AR-15 A2 rifle standard buttstock buffer spring is a critical wear item that keeps your rifle's recoil management system functioning reliably. Whether you're building a new AR or replacing a worn component in a trusted workhorse, this buffer spring is engineered to handle the demands of regular shooting, hunting, and training without compromise. Luth-AR's commitment to precision manufacturing and durable construction means you're getting a part that will deliver consistent performance year after year.
Buffer springs are one of those components that rarely get attention until something goes wrong—but they're the unsung heroes of your AR's operating system. This standard A2 buttstock spring cycles thousands of times, absorbing and returning energy from your bolt carrier group. When it wears out, you'll notice sluggish bolt action or inconsistent cycling. Replacing it is straightforward, affordable insurance that keeps your rifle running the way it should.
Luth-AR has built a solid reputation among AR builders and shooters for producing dependable parts that don't cut corners. This buffer spring reflects that philosophy: it's made to last and made to work, whether you're running a tactical setup, a hunting rifle, or a target gun. Stock one as a spare for your range bag or grab one for a rifle you're assembling—having a quality replacement on hand means you're never stuck waiting on parts when you want to shoot.

This is a standard A2 buttstock buffer spring, designed for AR-15 rifles that use the A2-pattern stock and receiver tube assembly.
Buffer springs wear over time as they cycle with your bolt carrier group. If you notice your rifle's recoil feels different, cycling seems sluggish, or you haven't replaced it in several years of regular shooting, it's a good time to swap in a fresh spring.
This is the buffer spring component. Confirm your full buffer assembly configuration before ordering to ensure compatibility with your rifle.
