Wilson Combat Flat Wire Buffer Tube Spring Features The Wilson Combat Flat Wire Buffer Tube Spring uses a 37-coil flat wire design that compresses more linearly than a traditional round wire spring reducing the coil stacking that can cause inconsistent buffer travel. That more consistent compression translates into smoother cycling and increased reliability whether the rifle is being run hard in competition or simply put through a high round count at the range. The flat wire geometry also increases both tensile and compression strength compared to conventional AR-15 springs helping the spring maintain its intended rate over a longer service life. Built from chrome silicon material the spring is engineered to resist the wear that eventually causes lesser springs to weaken and lose consistency. Finished in black steel and sized specifically for the AR-15 platform this spring is a straightforward drop-in upgrade that does not require any other modification to the rifle s buffer system. Because it lasts longer than conventional springs it reduces the frequency of replacement and the risk of a spring-related malfunction during a critical moment. Competition shooters benefit from the smoother more predictable cycling while recreational shooters gain the reliability and durability of a purpose-built upgrade part. For anyone looking to improve their AR-15 s buffer system with a proven American-made component the Wilson Combat flat wire spring is an easy addition.
