Quick question I couldnt find the answer to.... Was the RCO-A4 model's stradia lines calibrated against 62gr M855/20inch M16 or does it still use 55gr M193/20inch M16?

I will research this further, but after speaking to a friend who has several Trijicon sights, the answer to your question is 62gr. Although he says out to 300yds there is little difference between the two grain weights.

Thanks Dan. 62gr would have been my guess, but couldn't find any documentation that supported that.....
