The wait time is pretty dead on, as I just received my T4A about 4 months after it was ordered. Have them go ahead and install the pillars there and you should be good to go. They make nice stocks, let us know how you like the EH1, that is the stock I am looking at for a future build as well. The wait sucks, I just ordered a T5A as well, but I probably won't have the jack to finish that build before the stock gets here anyway.
