Ensure optimal performance with the right recoil spring - achieving peak performance and reliability from your firearm requires matching the recoil spring to the specific ammunition used. The correct recoil spring weight ensures ejected brass lands approximately 8-12 feet away. If brass lands too close, within a few feet, the spring is too heavy for the load, potentially causing cycling issues. Conversely, if brass is ejected beyond 12 feet, the spring is too light, which can also compromise reliability. To maintain consistent performance, replace the recoil spring every 3,000 rounds. This proactive maintenance step ensures smooth and efficient firearm operation, providing confidence and reliability.
