Features & Specs

• Two-Stage Forced-Reset Mechanism: The FRT-RD3 uses a true two-stage trigger pull with a defined take-up and wall, followed by a forced-reset function that returns the trigger forward automatically after each shot. This allows for rapid follow-up shots without modifying the firearm’s semi-automatic classification.
• Three-Position Ambidextrous Selector: Features a 3-position safety selector (Safe, Semi, FRT) that is fully ambidextrous, making it suitable for left- and right-handed shooters. The selector markings are clear and durable for quick identification under stress.
• Drop-In Compatibility: Designed specifically for HK MP5, MP5K, SP5, and SP5K models. Installs directly into factory trigger housings without drilling, filing, or permanent alterations. Includes all necessary springs and pins for a complete installation.
• Manufacturer: Rare Breed | Category: Triggers – Built with hardened steel components and precision-machined tolerances to ensure longevity and consistent performance in demanding conditions.
