Frequently Asked Questions

What is the "stand test" for an AR-15 Bolt Carrier Group (BCG)?

The "stand test" is a quick diagnostic for AR-15 BCGs. You attempt to stand the BCG upright on a flat surface using the bolt as the base. If the carrier immediately slides down, it indicates the gas rings are worn out or have "blown out."

Why did the PSA H&R M16A2 rifle fail at 2,000 rounds?

The rifle failed due to worn-out gas rings in the Bolt Carrier Group (BCG). This was identified using the "stand test," where the BCG could not support its own weight, indicating a loss of seal and potential function issues.

What components were involved in the PSA H&R M16A2 build?

The build featured an H&R M16A2 upper receiver and a Colt lower receiver, assembled by Palmetto State Armory (PSA). It had a 12.7-inch barrel.

What is the significance of worn gas rings in an AR-15 BCG?

Worn gas rings create a poor seal between the bolt and the carrier, allowing excessive gas to escape. This can lead to reduced cycling efficiency, potential short-stroking, and overall unreliability of the firearm.
