Colt AR-15 Large Pin/Sear Block Velocity Trigger Failed Install! 08Apr2022

When making the large pin Velocity trigger purchase I had thought it would work with the Colt large pin and sear block. Nope! Making mistakes so you don't have to! Lol! Deciding whether to have the sear block completely machined out? Did get the GG&G Dually weapon light rail mounted on one of my other PSA's though!
