I got a dilemma I will be recieving my XCR in about a week and I have both a 5.56 calibrated 2008 Elcan Spector DR and Eotech I could put on it. What do you guys think I should put on it? I am leaning toward the Spector DR and saving the Eotech for future purchases. But I haven't made up my mind yet.
