on the A or C zone of an IPSC torso, on the timer, from Rhodesian Ready, safety engaged, finger outside of the trigger, rifle held horizontally across the thighs. Average of 5 tries. 1.5 seconds, same thing at 50m, 1.9 seconds, 100m. With the modified open rear sight, AR, and trigger job. Nothing to it. That's the point. Use the gear that makes it easy. and stick to that gear, unless given an overwhelming reason to switch to something else. The weak hside shoulder is still about 1/4 second slower (despite the ambi-safet) It's also more prone to the occasional D zone hit. at such speeds.
