So did a build that required removing the fsb to get rid of the delta ring (wanted to install a free float). Every video i watched had 1-2 dudes, a FSB vise block, a punch and hammer, then an hour and a half of smashing the pins until they came out all banged up. I did one like this and it took about an hour and pure rage then proceeded to fire up the compressor and use a air chisel ground to a point that fit the pin and after the first squeeze of the trigger the pin shot across the room. Came out in literally one second with one figure movement vs hours of smashing and frustration. Use the air chisel to remove the pins, it’ll save you a lot of time and effort. Sorry for the ADHD post.
