The ELF Drop-In Match Trigger has been built for performance. The only AR-15 trigger using aircraft needle bearings, making for an incredibly smooth and fast trigger pull. Pull weight is so easy to adjust it can be done in seconds without removing the trigger from your lower receiver. A second-to-none AR- 15 drop-in trigger system that is strong and light, made of wire EDM machined, hardened A2 tool steel and lightweight aircraft-grade aluminum. Installation can be done in minutes using your AR’s original hammer and trigger pins. The match trigger may be ordered with a curved or straight shoe. The amazingly short takeup, glass-rod crisp break and next to zero over-travel can be compared to the finest custom 1911 triggers. Adjustability puts you in charge based on your current use. If you are looking for the finest adjustable trigger for your AR-15 platform, this is the trigger system for you.
