The Strike Industries Flat Wire Buffer Spring for AR-15 Pistol is a precision-engineered replacement spring designed for AR pistol builders and shooters who demand reliability and smooth operation from their short-barreled builds. Unlike standard coil springs, the flat wire design offers consistent spring rates and reduced friction, translating to more predictable cycling and less wear on your receiver extension and bolt carrier group over time. If you're running a pistol-length buffer system on an AR-15 platform, upgrading to this aftermarket spring is a straightforward way to enhance your gun's durability and reliability with minimal cost or effort.

Flat wire springs have become the go-to choice for serious AR builders because they maintain their geometry and spring rate better than traditional helical coils, especially under the demands of high-round-count shooting. Whether you're setting up a dedicated range gun, a home-defense AR pistol, or an SBR, swapping in a quality buffer spring is one of those small upgrades that pays dividends in consistency and longevity. Strike Industries' reputation in the tactical and competitive shooting world means you're getting a component engineered to mil-spec standards without the mil-spec price tag.

Installation is straightforward for anyone comfortable working on an AR platform—simply remove your charging handle, depress the buffer tube lock pin, and swap the old spring for the new one. No gunsmithing required. This is the kind of proactive maintenance and upgrade that separates a well-tuned build from one that just goes bang.
