Pressure switches are essential components for many AR-15 setups, offering a more discreet and controlled method of activating accessories like lights and lasers. This guide provides a comprehensive look at pressure switch mounting options for your AR-15, covering various installation methods, types of switches, and troubleshooting common issues. Understanding proper pressure switch mounting ensures optimal performance and reliability in any situation.
Understanding AR-15 Pressure Switches and Their Purpose
Pressure switches provide a hands-free activation method for accessories attached to your AR-15, most commonly weapon lights. Instead of manually pressing a button on the light itself, a pressure switch allows for activation through a cable connected to the switch, often mounted on the rail system. This enables tactical advantages, such as maintaining a firing grip while activating the light.
Types of Pressure Switches
Several types of pressure switches exist, each with its own advantages and disadvantages:
-
Push-to-Talk (PTT): These switches require continuous pressure to maintain activation. Releasing the pressure deactivates the light. They are common in military and law enforcement applications.
-
Momentary: Similar to PTT, but often with a more tactile "click" feedback upon activation.
-
Toggle Switches: These switches offer a simple on/off function. Once activated, the light stays on until the switch is toggled off.
-
Remote Tap Switches: These switches utilize a small, easily-concealed tap switch that activates the accessory upon a light tap. Ideal for stealth operations or situations requiring minimal movement.
Key Considerations Before Mounting
Before beginning the installation, consider these crucial factors:
-
Compatibility: Ensure the pressure switch is compatible with your specific light or accessory. Check manufacturers' specifications to avoid issues.
-
Switch Placement: Consider your shooting style and the intended use of the accessory. Optimal placement allows easy access without hindering your grip or manipulation of the weapon. Common locations include the handguard, pistol grip, or even on a sling.
-
Cable Routing: Plan the cable route carefully to avoid snags or interference with other components. Use cable ties or Velcro straps to secure the cable neatly.
Methods for Mounting an AR-15 Pressure Switch
Several popular methods exist for mounting a pressure switch on an AR-15. The best method often depends on personal preference and the type of pressure switch being used.
1. Mounting on the Handguard
This is perhaps the most common method, offering easy access and minimal interference with other components. Many handguards feature M-LOK or Picatinny rails, providing mounting points for pressure switch mounts.
-
M-LOK System: M-LOK systems are known for their sleek design and strength. Numerous M-LOK compatible pressure switch mounts are readily available on the market.
-
Picatinny Rail System: Picatinny rails offer wide compatibility with a range of mounts and accessories. Many pressure switch mounts utilize this system.
Example: A Surefire M600V weapon light with a dedicated Surefire pressure switch mounted on an M-LOK rail using a dedicated M-LOK mount.
2. Mounting on the Pistol Grip
This mounting option allows for a more intuitive and easily accessible pressure switch, especially during close-quarters combat scenarios. This method often requires a pistol grip with integrated pressure switch mounting points or an adapter.
Example: A BCM Gunfighter pistol grip with a pressure switch mount integrated into the grip itself.
3. Using a Sling Mount
Some pressure switches can be mounted directly to a sling, providing a unique placement option. This is ideal for users who prefer minimal rail space usage. However, it may require adjusting your sling's position for optimal access.
Troubleshooting Common Pressure Switch Issues
Even with careful installation, problems can arise. Here are some common issues and solutions:
-
Intermittent Activation: Check the cable connections and ensure proper contact. A loose connection can cause intermittent activation.
-
No Activation: Verify the battery in your weapon light and ensure that the switch itself is properly installed and connected.
-
Cable Interference: If the cable is interfering with other components, reroute it to avoid snags or interference.
-
Switch Failure: If none of the above solutions work, the pressure switch itself may be faulty. Replace it with a new one.
Conclusion: Optimizing Your AR-15 Setup with Proper Pressure Switch Mounting
Proper pressure switch mounting is essential for maximizing the effectiveness and reliability of your AR-15 accessories. By understanding the different mounting methods, types of switches, and potential issues, you can ensure a seamless and functional setup. Remember to always prioritize safety and follow manufacturer's instructions for installation. Choosing the right pressure switch and mounting location significantly improves your tactical capabilities and overall shooting experience.
