The Elftmann Service trigger is an adjustable drop-in trigger designed for AR-15 and AR-10 pattern lower receivers, giving the shooter the ability to set pull weight and overtravel to their preferred specification rather than accepting a fixed factory setting. Adjustable triggers allow the shooter to fine-tune the feel of the trigger to their shooting style, hand strength, and intended application — whether that means a lighter pull for precision work or a heavier, more deliberate pull for defensive use. The mil-spec pin size is compatible with standard AR-15 and AR-10 lower receivers using .154-inch trigger and hammer pins, covering the vast majority of mil-spec pattern lowers. Installation uses the factory trigger and hammer pins with no permanent modification required. For shooters who want to dial in a specific trigger feel across different builds or applications, the Elftmann Service adjustable trigger provides more customization than a fixed-weight drop-in at a price point between the SE and full match tiers.
