I have a 2T, and like it very much. I've had no issues which weren't related to #### I bolted on (Magpul BAD lever) or mags (POS LAR15 mags which require a ton of modification to run correctly; Magpul Gen M3 Pmags won't drop free without slightly filing the catch tab on the side.)
Rifle is decently accurate, though I had a 2R a few years ago that was exceptional for a rack-grade gun.
I installed a Geissle SSA trigger, which is an excellent upgrade IMO, though the factory trigger wasn't egregious. I also added a Magpul CTR and MIAD, and a Rainier Raptor charge handle.
