Well I just finished building up my first AR lower receiver. I figured doing it myself was the best way to learn exactly how these things work since I've really only handled an AR a couple times. Had a great time during the lower assembly now just gotta save some coin for the upper.
Specs:
Spikes Tactical stripped lower
