The safety selector on your Smith & Wesson M&P 15 is a critical component, directly impacting the firearm's ability to fire. Understanding its operation, different types, and potential issues is paramount for safe and responsible firearm handling. This guide dives deep into the M&P 15 safety selector, covering everything from its basic function to advanced considerations for customization and maintenance.
Understanding the M&P 15 Safety Selector's Function
The safety selector on the M&P 15, like on most AR-15 style rifles, is a lever typically located on the right side of the lower receiver. Its primary function is to prevent accidental discharge by blocking the firing pin's movement. The selector usually has three positions:
-
Safe (S): This position completely blocks the firing pin, rendering the firearm incapable of firing, even if the trigger is pulled. This is the most important position when the firearm is not in use or being actively handled.
-
Semi-Automatic (Semi or S): In this position, the firearm will fire one round per trigger pull. This is the standard firing mode for most shooting situations.
-
Burst/Full-Auto (F or Auto): Some M&P 15 variants might include a fully automatic setting (though these are less common for civilian models). In this mode, the firearm will continue firing as long as the trigger is depressed. This setting requires additional legal considerations and licensing.
Types of M&P 15 Safety Selectors
While the basic function remains the same, variations exist in the design and feel of the safety selector:
-
Standard Ambidextrous Safety: Many M&P 15s come equipped with an ambidextrous safety selector, allowing for easy manipulation with either the right or left hand. This is a popular feature for shooters who are left-handed or prefer a more versatile setup.
-
Enhanced Ambidextrous Safety: Some aftermarket selectors offer improved ergonomics and a more pronounced lever for quicker, more positive engagement. These often feature extended paddles for easier manipulation while wearing gloves.
-
Short-Throw Safety Selectors: These selectors require less movement to switch between fire modes. This can be advantageous in dynamic shooting scenarios.
-
Material Variations: Selectors are typically made of steel or aluminum. Aluminum selectors offer lighter weight, while steel is generally considered more durable.
Troubleshooting and Maintenance
While generally reliable, issues with the safety selector can occur. Some common problems include:
-
Stiff or Difficult Operation: This might be due to debris, wear, or improper lubrication. Cleaning and lubrication are typically sufficient to resolve this.
-
Loose or Wobbly Selector: This could indicate a worn pivot pin or damaged selector. Replacing the damaged parts is necessary in this situation.
-
Selector Not Engaging Properly: This is a serious issue requiring immediate attention. Do not attempt to use the firearm if the safety is not functioning correctly. Professional gunsmith assessment is highly recommended.
Customization and Upgrades
Many aftermarket safety selectors offer improved ergonomics, durability, or aesthetics. Upgrading the safety selector is a relatively straightforward process for experienced gunsmiths or individuals with sufficient knowledge of firearm mechanics, however, it is crucial to ensure compatibility with your specific M&P 15 model.
Conclusion: Prioritizing Safety with Your M&P 15 Safety Selector
The safety selector on your M&P 15 is not merely a component; it's a vital safeguard. Understanding its function, recognizing potential issues, and performing regular maintenance are crucial for responsible gun ownership. Always prioritize safety and handle your firearm with the utmost care. Consult a qualified firearms instructor or gunsmith if you have any questions or concerns about your M&P 15 safety selector or any other firearm components. Remember, safe gun handling practices are paramount.
