15T adds a fold down front sight, 4 rail forend (which free floats the barrel), and rail covers.
YukonGlocker said:The 15T is a great deal if you plan to mount things on the railed forend. And with the flip down sights, it is ready for any optic you want.
I don't have any use for the railed forend, so the 15A is the ideal setup for me. :wink:
