I kind of suspicioned that, but it's nice to hear it from someone with more knowledge. My long range experience is limited to hi-power, M-14, and combat rifle, M16A1. No scopes in either discipline. I only got to shoot the 14 at the Winston P. Wilson matches once. I shot OK but nowhere near the best there. The longest stages were @ 1,000 yds. I shot combat rifle several years with the longest stage @ 600. They added that one with issue of the then new M16A2 and its better sights plus the new 60 gr. green tips if I remember correctly. My last match was the all-army at Fort. Benning. I shot pretty good and had a blast. It's the only thing I miss about the guard. Good luck, Troy
