time will tell. i think i will probably leave it alone for a while. i have a stripped lower coming from PSA and I am deciding if I want to try my hand at the NFA game. If I decide against a SBR, i will probably buy an Aimpoint or something. If I go the SBR route, the money will go towards an upper.
Glad to see all this positive PSA feedback. Once they get their growing pains out of the way, they are going to be a force to be reckoned with in the AR world. Even more so than they already are. Nice shootin!
