Troy Industries ambi safety assembly with the direct thread version uses threaded interface instead of cross pin. Cleaner install. Both sides function at 90 degrees. Detent click is positive. Semi-auto version is what most builds need.
Troy Industries ambi safety with direct thread interface works correctly. Both sides function at 90 degrees with positive detent. The price feels a touch steep for what is essentially a quality milspec ambi. Function and reliability are excellent.
direct thread design means no roll pin holding the paddles, you can swap paddle sizes if troy makes another option. detents engage positive. fit on a mil spec lower is correct, no slop
