Thinking of getting an AR15 pistol in .300 AAC (Blackout), probably an 8" bbl. that could later be suppressed. This would be a home defense and travel backpack pistol, so I don't need fancy and expensive...just dependable and accurate. Obviously there are lots of options, but I've kind of narrowed my choice down to Palmetto State or Diamondback (FDE or Coyote Brown). The DBs come complete and are manufactured locally close to me...but I'm also looking at buying a PSA upper and PSA complete lower and putting it together myself. Any thoughts on either of these two choices? Value, fit and finish, dependability, accuracy? Thanks in advance.
