Can anyone tell me where to find a good detailed AR manual. I just recieved one from gun guides and disappointed. I'm wanting one that shows more than just a basic cleaning tear down. Is there one out there that would take me step by step with something like taking a barrel and putting it another one on. Example I am wanting to take my Colt from its currect 16'' m4gery config. back to its original 20" confg. Unfortunately I am one of those who needs lots of pictures and I am new to this hobby although pretty mechanical.

Thanks in advance.

LOL, nah, lots of info here, takes time to find it all. There's also a step by step barrel replacement thread here too: www.ar15.com/forums/topic.html?b=3&f=4&t=226782

O.k. I think I can do it. But here is my other question. Do I need to worry about headspacing? I bought these parts (16'' barrell w/gas tube, ft upper, bolt assembly, delta ring and barrel nut) from my buddie to help him out and he purchased them new, but seperate. They are all RRA parts. Can I just assemble it and go, or is there more to it.

Thanks again

Generally not. Headspacing is done by the bolt and receiver extension. If your bolt and receiver extension are quality products they should have been made right at the factory. It's why I don't skimp on barrels or bolts and get cheap stuff.

That being said, I still check by rifles periodically with a USGI 'Field' gauge to make sure headspace hasn't increased beyond what is considered safe.
