Wiz, looks nice! What barrel/sight block/rail setup is that?
details are actually in my WTS add but its pretty much all YHM parts with the spikes enhanced lower parts kit.
But I will copy them over here.
ETA:
I built this around the free float tube and have run one 30 round pmag through it to function check it which it preformed flawlessly. I love the way the rail extends around and past the FSB and the flip up front sight sits down in the rail.
This rifle looks amazing and is extremely well balanced
