Here's my dilemma. I can buy a PSA (or DPMS) for about what I can build one ... and I know the components will be compatible. Or I can do endless research and take a huge amount of time and spend about the same dinero to build one myself. Yes, I know all the relative merits of 'buy vs. build'. I just can't decide which makes more sense for me. I'm not asking you to tell me what to do; I'm asking you to tell me what you've done ... and why. Please limit your responses to AR-10 builds. It's that exceptional case that is most of the issue here. Thanks in advance.
