With the right sight and lots of practice, ABSOLUTELY.
Skinner Sights make wonderful peeps. The post (ring) is threaded on the inside for an insert (peep). If you screw the peep out and just use the ring, you get an incredible FOV (i.e.: rapid target aquisition with adequate accuracy). If you use the peep inserts, you get more accuracy with a cost of FOV.
As to the practice: if you haven't used a peep before, it takes some convincing of your "brain". It's not like a buckhorn or blade sight. You shoot both eyes open and ignore the rear sight. Put the front sight on the target and concentrate on it. The rear sight will "ghost", thus the name. Your brain will automatically center your vision in the ring. You can only screw this part up by thinking and trying to center the front sight in the rear ring. You oncentrate on the front sight and your brain does the rest. This is what makes the ghost ring or peep type sight so great for aging eyes. You don't have to focus on two sights (front/rear), only the front.
