Im trying to install the ARC Fire v2 on my Ruger AR-556 and running into some issues.

Firstly, the trigger is not dry firing in Semi or ARC unless i first depress the disconnector and the hammer moves up to a slightly higher position, and then it will fire if the ARC fire lever is positioned toward to muzzle end.

Second, even after making room by grinding away the high shelf for the lever to travel back far enough, im still getting binding when charging the BCG. Do i also need to remove material from the upper?

Ive been looking all over and cant seem to find a guide that clearly explains the issues im having. Any help would be greatly appreciated!
