Best Base AR-15s

What Makes A Good Base AR-15? 

Quality components are the foundation of a successful build. Essentially, any part you do not plan to immediately replace must function flawlessly right out of the box. Many reputable manufacturers produce excellent base model ARs; look for the following to narrow your selection:

  • Matched Upper / Lower Receiver - a receiver set made of 7075-T6 aluminum will fit together perfectly and hold up over time
  • M-LOK Handguard - look for a rifle with an M-LOK handguard already installed and you'll have one less part to upgrade
  • 4150 Steel Barrel - don't skimp when it comes to barrels or you may end up ordering a costly replacement you hadn't intended to purchase
  • Black Nitride Bolt Carrier Group - a rifle with a black nitride bolt carrier group will function more reliably and will also last longer

For most shooters, other parts (like stocks, grips, triggers, sights, muzzle devices, etc.) are more subjective and thus, are more likely to be swapped out and upgraded during a build. Some may even opt for a different style of handguard, a stainless barrel, or a nickel boron bolt carrier group. The above criteria merely serves as a baseline for what you should look for in a base AR-15 for your next project.

Maybe you'd like a base rifle with your favorite stock already installed so all you have to do is throw on an optic, swap out the trigger, and thread on your favorite muzzle device. Or, perhaps you want to a plain mil-spec AR to act as a blank canvas for your dream build. Whatever you're looking for, we've got the AR-15 for you!
