I’m relatively new to guns (own an XD .9mm and .40sc) and have zero knowledge of rifles. Is there any one source where I can go and read up on them (like difference between ar15 and m4)? I’m mostly interested in learning the parts, what they do, what to purchase, and finally how to assemble one. Any suggestions?
go to ar15.com. Find the forums for the ar15 general discussion and read. There is a few good articles there on how to assemble your own lower from the parts kit, including video. I am in a similar situation with you that I only own 1 handgun (before it got lost in that boating accident) and might be interested in an AR15. I've done a lot of reading online. Also, get together your questions and go visit Dan at Gun Connection, him or someone there can answer anything.
Wiki gives a good primer. http://en.wikipedia.org/wiki/M4_Carbine
When it comes to firearms, there can be no stupid question. My thoughts are it is better to ask the dumb question and risk being laughed at, then making an assumption and potentially hurting yourself or someone else.
