I have seen plenty of the triple "T's" and always assumed they came from the factory but that's why I come to this site is to learn something new. Perhaps it is that these 15's are considered so accurate that folks wanted to dress them up with target accessories, I will take one any ole way and until things went bat **** crazy you could pick one up in 98% condition for $500 and now I seldom see them for under $700-800 and the supply is less than 50% of what it use to be, good thing you got yours.
