Luth-AR AR15 Trigger Assembly Features The Luth-ar Trigger Assembly houses its internal components in a 6061 hardcoat anodized aluminum frame providing both durability and dimensional consistency for a reliable drop-in fit into an AR15 lower receiver. Internal components are precision cut using an EDM process from A2 tool steel then heat treated to 40-45 HRC for long term wear resistance under repeated use. Stainless steel bushings and springs round out the internals contributing to a trigger pull that remains crisp and consistent shot after shot. The result is a 3.5 lb single stage pull that breaks cleanly giving shooters a noticeable improvement in feel over a stock mil-spec trigger. Because the assembly is a complete drop-in unit installation is straightforward and does not require extensive gunsmithing or trigger job experience. The anodized black finish matches most AR15 lower receivers for a factory appearance after installation. This upgrade benefits competition shooters hunters and home defense rifle owners alike who want more precise control over their shot break. The Luth-ar Trigger Assembly is available for sale at GrabAGun for AR15 owners looking to improve trigger feel with a reliable single stage drop-in unit.
