I've had the opportunity to shoot a T3 Lite, and it is a really nice rifle. They also get high ratings in reviews etc, with the only drawback considered to be the polymer stock(Conservative hunters want their wooden stocks....).
Using 5.56x45, you won't have any serious problems with recoil, but if you choose to switch to a larger caliber sometime in the future, you might want to add weight to it.
