Luth-AR LR-MTA Modular Trigger Assembly Single-Stage Drop-In

The Luth-AR LR-MTA Modular Trigger Assembly is a single-stage, drop-in trigger upgrade designed for AR-platform rifles. The housing is machined from 6061 aluminum with a hardcoat anodized finish, while the internals are precision EDM-cut from A2 tool steel and heat treated to 40–45 HRC. SST bushings and springs deliver a crisp, consistent 3.5 lb trigger break. Self-contained drop-in design simplifies installation.
