When I and my fellow computer hobbyist buddies (geeks) first got into building computers in the 1980s, we found the IBM platform to be an excellent computing platform on which to build. The reason being that it was a ubiquitous platform, and everybody and their brother made parts for them. The common term back then was the "IBM Clone" that went by many different brand names, and parts were so readily available that hobbyists could build complete computers from scratch cheaply and easily.
The AR-15 rifle platform has become a similarly ubiquitous platform for beginning and advanced rifle builders alike. Parts are available practically everywhere to build your rifle in your own unique configuration. You don't even have to be an advanced or experienced gunsmith to build a rifle in the AR platform, but you do at least have to know a bit about firearms components, how they function, and what parts will or will not be compatible with other rifle components.

I came across an excellent video this week from The Daily Shooter that breaks it all down and gives some great explanations of the AR rifle platform. William does an excellent job of breaking down the upper and lower receivers, bolt carrier group, and other components unique to the AR platform
