How to Build an AR-15 – A Beginner’s Overview
If you’re new to building rifles, the AR-15 platform is a fantastic place to start because of its modularity and widespread parts availability. Here’s a simplified step-by-step AR-15 build process:
Start with the lower receiver – This is the serialized firearm and the legal “gun” part.
Install the lower parts kit – Trigger, safety selector, magazine release, bolt catch, and pins.
Add the buffer assembly – Buffer tube, spring, and buffer.
Attach your stock or brace – Adjustable or fixed.
Move to the upper receiver – Install the barrel, gas block, and gas tube.
Attach the handguard – Free-floating or drop-in styles.
Insert the bolt carrier group & charging handle – The heart of your rifle’s action.
Secure the upper and lower together – Pivot and takedown pins.
Function check – Ensure everything moves and cycles correctly.
Note: In our Build It, Check It, Shoot It class, you’ll learn not just how to assemble these parts, but why each part matters and how to select the best one for your needs.
Common Mistakes to Avoid When Building an AR-15
Even experienced builders can make errors that affect performance or safety. Our instructors at Republic Gun Club see these most often:
Over-torquing barrel nuts – Can damage threads or affect accuracy.
Incorrect gas block alignment – Causes cycling issues.
Forgetting proper lubrication – Leads to premature wear.
Improper headspacing – Can create dangerous pressure problems.
Mixing incompatible parts – Not all AR-15 parts are truly “mil-spec.”
When you build with us, we help you avoid these mistakes and ensure your rifle is 100% range-ready before you fire a single round.

Choosing the Right AR-15 Parts for Your Build
Not all AR-15 builds are the same. Here are a few factors to consider before buying parts:
Purpose – Will this be a home defense rifle, range toy, competition gun, or hunting rifle?
Weight – Do you want it lightweight for mobility or heavier for stability?
Caliber – 5.56 NATO is most common, but others have unique benefits.
Trigger type – Mil-spec triggers are durable, but match triggers offer precision.
Optics & accessories – Planning for scopes, red dots, or lasers changes rail choices.
At Republic Gun Club, we walk you through each choice, ensuring your build matches your goals.

Still, it’s important to build your rifle within federal guidelines, which is another reason our Build It, Check It, Shoot It class is so valuable — we ensure your rifle is compliant and safe.
