Luth-AR LR-MTA Modular Trigger Assembly AR-15 Single-Stage 3.5 lb Drop-In - Black

The Luth-AR LR-MTA Modular Trigger Assembly is a single-stage drop-in trigger purpose-built for the AR-15 platform. Its housing is CNC-machined from 6061 aluminum and finished in hardcoat anodized black, while the hammer, trigger, and disconnector are precision-cut from A2 tool steel using EDM, then heat treated to 40-45 HRC and finished in black nitride for long-lasting wear resistance.

Tuned to a clean 3.5 lb trigger pull, the LR-MTA delivers a crisp, consistent break suited to duty, defensive, and precision AR builds alike. As a true drop-in module, it installs directly into a standard AR-15 lower receiver without any custom fitting, giving shooters a straightforward path to a noticeably improved trigger feel right out of the box.
