Trigger cassette - OpticsPlanet Exclusive RISE Armament RA-242 Gen 2 Enhanced Rifle Trigger

I had a heavy, gritty, horrible trigger in my AR-10. I bought this Rise Armament drop in cassette and the difference is like night and day! Feels like a glass rod; no movement, then breaks! I can now evaluate the barrel instead of fighting the trigger. My groups have shrunk considerably now that I have a good trigger.Installation was as easy as putting butter on toast. I liked it so much I bought another!
