Now you need an action block, an armorers wrench, a vice and a torque wrench.
Brownells has some good videos for AR assembly. When you torque the barrel nut you might have to tighten and loosen then tighten it a couple times for it to line up correctly. Just take your time and enjoy it. There is some real personal satisfaction from build your own rifles.
