The Timney AR-15 Competition Trigger in the 3 lb curved version (brand part no. 667S) is the trigger Timney calls the gold standard for AR-15 triggers since its 2005 release. It is a fully drop-in cassette that delivers a crisp, clean break at a fixed pull weight, with no gunsmithing or fitting. It suits competition shooting, range work and any build where a lighter, cleaner trigger will help accuracy.
