Luth-AR Trigger Group 3-Piece Features The Luth-AR Trigger Group 3-Piece bundles a single stage trigger hammer and disconnector together giving builders a matched set rather than three parts sourced separately and hoped to work well together. Built for AR-15 platform rifles the set is intended to deliver a smoother more consistent trigger pull than a worn or mil-spec factory setup. The manganese phosphate finish in black provides a durable corrosion-resistant surface that holds up to repeated dry fire and live fire cycling. Because springs are not included this set is best suited to a rebuild where the existing springs are still serviceable or a full fire control group upgrade is already planned. Installation follows the same basic pin-and-spring process familiar to anyone who has worked on an AR-15 lower making this set a straightforward upgrade for home builders and armorers alike. The durable materials used in the trigger hammer and disconnector are intended to provide long-lasting performance under regular use. Replacing all three components together also helps ensure proper geometry and engagement between the parts since mixing new and worn components can affect trigger feel. For shooters looking to improve an AR-15 s trigger pull without stepping up to a complete drop-in unit the Luth-AR Trigger Group 3-Piece offers a simpler cost effective path.
