Simple and solid - Timney Triggers AR-15 Competition Trigger

Installation was quick and easy. You get an installation chart that has a lot of explanatary photos. Simple tool needs. A part of my old trigger actually sprung out as it was under spring tension. Caught me by surprise but not a big deal. You have to move the spring fingers aside on the Timney to access the installation screw holes then reposition when done. This was a single stage trigger so absolutely no takeup on the pull. Trigger broke very cleanly. Biggest decisions for you - trigger pull weight and whether single stage or 2 stage trigger.
