How To Not Forget Anything While Building Your Own AR.

So you have decided you want to build your own AR. You have watched a ton of YouTube videos and decided that it doesn’t look too difficult and you’re ready to take the plunge. But where do you start? What components do you buy? How do I know I have everything I need?

First you need to answer some questions.

  • What is the intended purpose of your build? Hunting, target shooting, home defense, competition shooting? Let the purpose drive the build.
  • What tools will I need? I recommend a decent AR building set of tools. You will spend $150+ on these, but you will use them for general maintenance and upgrades. Also lets be honest, nobody ever builds just one AR….LOL
  • What is my budget. Set a budget but expect to go over it, I did with my first just, by a couple hundred but it will happen.
  • What are all of the parts I need to buy? This is the million dollar question. Nobody wants to get started on a build and realize you forgot to buy a gas tube and have to wait a week for one to be delivered to you. Or trudge around trying to find one in stock at a gun store.

Upper Receiver Assembly

  4. Bolt carrier group: Choices, Coatings, Steel Grades, Calibers, and Weights. $80-250+
  5. Barrel: Choices, Steel Grades, Calibers, Twist Rates, Lengths and Gas Lengths. $100-500+

Extras

  1. Magazines based on caliber chosen and capacity of cartridges it holds. This can vary by state law. Again do your research. $15-30+
  2. Ammo. Based on caliber chosen. Ammo prices are crazy right now and availability is limited. Good luck is all I can say…
  3. Gun Case, Range Bag. Tons of options and styles, have fun making a decision LOL. They are typically $50-200+, and I don’t know of a single range that will let you walk in with an un-cased weapon.
  4. Sights: Iron Sights to Red Dots to Scopes. You have more choices here than any other category. Let the purpose decide the choice again. Research is your friend. $50-1,000s

This is by no means a complete list of all available options or upgrades but this checklist will get you everything you need to build a rifle and start shooting… As you can see from pricing you can spend $600 or you can spend $1,000s it’s up to you. Typically as with most things the more you pay the better quality you get. There are still a few companies out there making quality American products at affordable prices. If your build comes in under $500 I wouldn’t bet your life on it. That is range toy prices. The top 4 places to spend your money in my opinion are 1. Barrel 2. Bolt carrier group. 3. Lower parts kit. 4. Receivers.

As always shoot straight, be safe, and have fun.
