Welcome to the 15T Club!

i LOVE mine. have added a Bushnell TR25 red dot and a magnifier.
put a Magpul CTR stock on it and am getting a QD plate for my Magpul sling. will be able to go two point to single point with the Magpul adapter.

IMHO, the 15T is right in the middle and has most of the basics that most want.
