Programmable Fire Control Unit (FCU)

The SLR 3.5 model is equipped with a programmable Fire Control Unit (FCU), offering superior control and a refined shooting experience.

• Customizable Firing Modes: Easily switch between Single Shot, 2-Round Burst, and Full-Auto modes to match your tactical needs.
• Enhanced Trigger Feel: The intelligent FCU ensures a smoother, more responsive trigger pull compared to standard blasters.

Troubleshooting: FCU Reset Guide

If your SLR experiences irregular firing, a quick reset of the Fire Control Unit often resolves the issue.

Follow these steps to reset the FCU:

• Set the safety selector to SAFE.
• Press and hold the trigger and do not release it.
• Continue holding. After about 3 seconds, you will hear three beeps and see the trigger's blue LED flash three times.
• Keep holding the trigger until a total of 8 seconds have passed. You will then hear one final beep and see the blue LED flash once.
• Release the trigger. This sequence confirms a successful FCU reset.

Pro Tip: After a reset, you may need to reconfigure your preferred firing mode.
