The finest AR trigger I have used so far. At some point in the future I hope to get a SD-3G but for now this will more than suffice.
The first stage is short, but just long enough to give you a little moment of pause which asks. "Are you really sure that you want to shoot?" That could prove life saving if one was aiming at something that you did not want to destroy and could prove very helpful in a court of law.
The second stage breaks like a glass rod.
