Timney Impact AR Trigger — AR-15 (3-4 lb)
The Timney Impact AR is a premium drop-in cassette trigger built specifically for AR-15 rifles. It delivers a crisp break between 3 and 4 pounds (~1.4 to 1.8 kg), a short positive reset, and installs in minutes with no gunsmith or fitting. Hand-assembled, tested and calibrated individually in the USA, it is backed by Timney’s Legendary Lifetime Warranty.
Two shoes to choose from — Curved or Straight
Select the trigger shoe that fits your shooting style :
- Standard Curved Trigger : classic curved shoe, familiar feel, ideal for duty, dynamic and general-purpose shooting.
