Very nice rifle for a great price! It's hard to beat PSA when it comes to bang for the buck. Just mix in charging handle, rear sight, sling, magazines and a few hundred rounds for a good time!
If you haven't ordered yet my only suggestion would be to look at their LW midlength.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
