First Time Build Upper Assembly Question

[cory]

I thought I'd update this thread as I've completely rebuilt the upper on Loki. I swapped out the 5.56 spikes tactical 16" M4 barrel (good barrel) for a 14.5" LW .223 wylde barrel from Mark at PF.

At this point why not upgrade the hand guard, gas block and FH, at least that was my logic. I had to pin the FH, so I wouldn't get the chance to change it later.

I also added an ACOG TA31f to her. There are certainly better options out there for the price, but I've got so much time behind one from a few ok several years back that I felt very comfortable with it.
