The life expectancy of the M500A1 service shotgun is how many rounds?

The life expectancy of the M500A1 service shotgun is generally considered to be around 10,000 rounds. This figure accounts for the shotgun's durability and design engineered for extensive use in various operational conditions. While firearms may continue to function beyond this expected round count, 10,000 rounds is a benchmark representing the point at which significant wear may start to affect reliability and performance. This standard is derived from military and law enforcement usage, where maintaining firearm reliability is crucial. Understanding this life expectancy helps in planning maintenance and replacements within tactical units to ensure that equipment remains in optimal condition for readiness and effectiveness.
