re: Official AR-15 thread

After about a month of hunting for a deal I picked up a PSA lower last week. I happened to be looking at their site before anyone posted it on AR15.com and was able to score one before the crowd. Thinking about matching up a PSA upper and will prob go with a PSA lower parts kit. So far I can't find any reason to not just use a PSA upper instead of a BCM. Will build this one up and then probably look to do it again. My buddy has a rock river with a bull barrel that doubles as a tack driver and that is really making me want to re-create it.
