Any one know what the
T numbers are on the sight rail of the sport 15 ?
I’m thinking it has to do with sight picture and distance maybe but I’m not sure

The T-numbers are a reference for return to zero attachments. (optics, night vision and lasers)

Really no use unless you are swapping stuff around a lot and they have RTZ mounts.

Just a reference point for mounting optics.

Thanks, been shooting with the flip up mbus that came on it and seems to be doing very good, I might opt for a scope later on.
Thanks for the Info
