Building an AR is not that difficult. Other than a couple of special wrenches, one for the barrel nut other for the receiver extension tube, I forget the proper name, that holds the action spring, an action block so you can hold the upper in a vice will be very desirable, I guess not absolutely necessary, but it will help a lot. Torqueing the barrel nut properly so one of the notches lines up with the upper receiver hole for the gas tube is a pain. I built most of mine with gas piston operating systems, and assembly is basically the same, just align the nut the same ( for operating rod vs gas tube) and go. Lowers although a bit more complex with trigger group, bolt release, mag release, are much easier. The main thing is to look things over and go slow.
