Premium-quality buffer spring helps ensure consistent, dependable operation for tens of thousands of compression cycles. Perfect for the high-volume tactical or competition shooter who needs a finely tuned spring that delivers its full power as reliably on the 50,000th shot as it did on the first. Made from chromium-silicon steel alloy selected specifically for its hardness, heat resistance, and ability to withstand high stresses—the same alloy used for valve springs on automobile engines. Cryogenically treated to relieve internal stress, and surface impregnated with proprietary Plate+ molybdenum disulfide lubricating coating. Carbine model for CAR-15/M4 available in Standard Weight that matches your gun’s original factory spec or Extra Power that keeps the bolt closed a bit longer, which helps some carbines cycle better and eject more positively. Standard-weight A2 Rifle spring fits fixed-stock rifles with A1/A2 receiver extension tube. All kits include an extra-power extractor spring that aids in complete extraction and ejection of spent shells, even from a tight or dirty chamber.
