AR15 weapons are for a serious use and if you don’t know a few things about building this weapon, it can and will be a little overwhelming. If you are building a AR15, there are lots of mistakes that can be made such as incorrectly aligned gas blocks, gas tubes, hammer springs reversed or under the trigger pin, loose barrel nuts, loose castle nuts and more. You need to know what you are doing if you want to build your own AR15.
- It is possible to learn the mechanics and workings of an AR without building it yourself.
- The greater reliability of a factory built gun is better for learning about them than trying to build one.
- It is difficult to reliably get components and put together an AR alone as a first time user as there are many things that can go wrong.
“By all means build a custom AR, but I highly recommend buying a good factory built AR15 as a starter. A factory built gun will generally be assembled correctly and there will be a warranty if there are any issues.”
