For shooting at the range I've been using a Sightmark Tactical Red Dot on my Storm, mounted mid-rail. After shooting my first match with it, I like it for accuracy but not for speed - it's a smaller tube and re-acquiring the dot can be slower with fast movement.
I'm switching it out for the Ultra Shot Plus, which has some interesting choices - 5MOA dot, 3MOA dot with 50 MOA ring, etc. - and mounting it as far to the rear as I can to get the widest field of view and fastest re-acquisition.
I'll find out how well this works over the weekend (not counting sighting it in this week) but I'm interested in others choice of optics for PCC, specifically around rapid acquisition at the typically shorter ranges we're shooting at.
