Engineered specifically for the PSA Rock 5.7 platform, the 5.7 Rock Device is a fully CNC-machined component designed to replace the factory disconnector. By harnessing the firearm’s natural cycling energy, it mechanically forces the trigger forward after every discharge, delivering a remarkably crisp, reactive reset.

By automatically resetting the trigger upon cycling, this device facilitates lightning-fast follow-up shots while strictly maintaining one round per trigger pull. The result is a dramatically enhanced trigger feel that maximizes practical firing speed without sacrificing control.

Precision Construction & Metallurgy
100% CNC-Machined: Precision-milled from solid billet for exact geometry and seamless interface with OEM fire control components.
Heat-Treated D2 Tool Steel: Selected for exceptional hardness, toughness, and superior wear resistance under sustained, high-volume firing.

Clear Hardened Finish: A durable clear coating protects against friction, corrosion, and surface wear while preserving the clean look of raw, precision-milled steel.

Ideal for custom builders, advanced hobbyists, and shooters looking to push the PSA Rock platform beyond stock trigger limits.

Final Fitment Note
Due to manufacturing tolerances across host firearms, minor hand-tuning or polishing may be required for optimal operation.
