I have a Model 2T Left hander. I have had it about 2 months only have a few hundred rounds through it. No problems so far no FTFs, jams or need to force the bolt withthe FA. The main shooting I have done was to try different ammo, to see how it does with cheap steel stuff vs better quality brass. No specifics but it shot everything well. I have had a ton of stuff going on that has limitted my time at the range but with graduations and all the kids school stuff done I expect more time on the range. I should be getting a Fed Ex delivery with a bunch of toys for it Weds. I ordered mine directly from Stag and have an A2 stock on it. I can hear the buffer spring and don't know if that is normal or not. Has a little bit of a slinky sound. I bet if I put bore snake in the compartment it would quiet it down. Feels realy nice and looks very well put together. No slop or wiggles anywhere. I am pretty much of an AR noob but I am very happy with my decision. And it is nice not have brass flying across my filed of vision. Lefty.
