Zman, can you talk to some of your SWAT buddies about leaving cover on front of red dot please? Looks like it is counter intuitive but leaving front covered when in transition low light to day light seems to speed target acquisition? Example, going from out doors breaching to indoors. I experimented this weekend with electrical tape over front of red dot and shot a precision target at high speed. Oddly enough I could see everything. It was like the tape was not there. Very odd.
