How to my First AR15 Build

General Discussion

I am in the process of building my first AR15 and could use some info. On the how’s, Do’s & Dont’s?

Well, there are plenty of Youtube videos that show how to do it. But “building” has several definitions. So some questions for you:

  1. are you buying a complete lower? If yes, then that part is done. If not, watch some youtube videos on how to assemble a lower. You will need the following tools:
    Vice
    lower vice block/Magpul bev block/etc.
    Armorer’s wrench
    Roll Pin Punches
    Gunsmith hammer (brass on one side, plastic/polymer on the other
    Tape (to tape the receiver when you install the bolt catch so you don’t scratch it
  1. Are you buying a complete upper? If not, you will need the following:
    Vice
    vice blocks/reaction rod/upper vice tool
    Armorer’s wrench
    Allen Wrenches (for gas block screws and whatever rail you want)
    A wrench for the muzzle device
    barrel blocks to install said muzzle device

If you buy a complete lower and a complete upper then just put them together. If not, then watch youtube videos (lots of good ones) and BUY THE RIGHT TOOLS (I can’t stress that enough). IMO if you build one, you will build more, so the tools will pay for themselves. Lastly, if you have questions, just ask. Many of us on here have years of experience building, and are happy to help. But be forwarned, there is no cure/pill/medical cure/etc, for Black Rifle Disease (BRD). Once you have it, you have it, and to be honest, it can be contagious also.

I can confirm this, I have brd. I’ve been diagnosed for a couple years now. I thought different colors or painting would cure me…:man_facepalming:

My advice…

Don’t.

As soon as you build your first one, you’re gonna want to do another. Then another. Then…

Next thing you know, you’ve gone from slapping a built upper onto a built lower; to finishing your own 80% lowers and assembling the entire firearm from a pile of pins, springs, and nuts.

But, seriously, it’s not hard. A custom built rifle is a ton of fun; my only advice is to be prepared to do some troubleshooting and tuning when you start deviating from the ‘standard mil-spec 5.56 carbine’
