Re: AR15 Uppers

You need a receiver block, barrel wrench and torque wrench. It takes about 10-30 min to put it together if you are using a barrel that already has a pinned fsb or if you are using a screw on gas block. If you have to drill and ream the barrel to pin on a gas block then it gets more complicated.
