Frequently Asked Questions

What are the most common mistakes when building an AR-15?

The top mistakes include lack of planning (purpose/budget), skimping on critical parts like barrels and BCGs, overspending on lowers, ignoring integrated features, prioritizing looks over quality, using unmatched receivers, employing incorrect tools, improper barrel installation, settling for subpar parts, and using reloaded ammo or neglecting maintenance.

Why is proper barrel installation crucial for an AR-15 build?

Improper barrel installation can lead to significant safety risks and poor firearm function. It's essential to use a torque wrench for correct tightness, a reaction rod for stability, and headspace gauges (Go/No-Go) to ensure the headspace is within safe specifications.

Which AR-15 components should not be compromised on quality?

The barrel and the Bolt Carrier Group (BCG) are considered the 'heart' of the AR-15. These components are subjected to high pressures and stresses, so opting for high-quality, properly tested parts (high-pressure tested and magnetic particle inspected) is crucial for reliability and safety.

What tools are essential for a successful AR-15 build?

Essential tools for an AR-15 build include a roll pin punch set to install pins without damage, bench blocks to support receiver components, a torque wrench for precise fastener tightening, a reaction rod for barrel installation stability, and headspace gauges (Go/No-Go) for safety checks.
