I think if your stock fits you properly a conventional mount is just as fast and the optics are significantly better with more options.
Another Jedi rifleman ex-spurt who doesn't own a shooting timer.
I dont consider myself a Jedi but after having the opportunity to train along side men such as Bennie Cooley and Michael Voight I have used a timer once or twice to see if I could pick up a speed advantage. After putting it on the clock many times in training and matches my experience leads me to a true zero magnification like an aimport or eotech for CQB applications (mounted almost anywhere on the rail). As soon as the range extends a bit or if magnifaction is needed for target identification I would rather have a simple 1.5x6 mounted in a conventional manner. If scout optics were a speed advantage there would be plenty of guys running them.
I have tried the scout concept twice for extended periods, once on a .35 Whelen and once on a gunsite scout at the ranch. I saw merit in both but could not see enough advantages to a conventional scope except in very narrow applications. I encourage everyone to experiment and find what works for them and apply it in the field accordingly.
