I don't have a kit or reciever and have very little experience with AR's.  My brother has an AR-10 and overall it does not seem that complicated to me.  How hard is to build an AR-15 from a stripped lower and one of those J&T kits?  What kind of special tools do I need?  I went to the Mid Missouri AR15.com shoot this weekend and had a really good time.

FWIW- I've built one, buying more parts for 2nd  build as we speak.  Shot'em for years.
The only special tools I would buy are roll pin punches.  The instructions list a couple of others, but you really don't need them.  Here are the ones I bought.  BTW the instructions are great and if you have any mechanical ability at all you can build one from the kit.

These punches help keep the punch attached to the roll pin while driving.  It is possible to get by w/o these, and some folks do get by w/o them.  IMHO they really help.

good luck!  I hope the "Black Rifle Desease" bug doesn't bite too hard.
