Frequently Asked Questions

How do you field strip a Colt AR-15 A2?

To field strip a Colt AR-15 A2, first ensure it's unloaded. Separate the upper and lower receivers (this model may have a Chicago screw). Remove the charging handle and bolt carrier group. Disassemble the bolt carrier group by removing the firing pin, cam pin, and bolt. Clean all components thoroughly.

What are the key components to clean on an AR-15 bolt carrier group?

Key components to clean on an AR-15 bolt carrier group include the bolt itself, the carrier, the firing pin, the cam pin, and the gas rings. Pay close attention to carbon buildup, especially around the gas rings and the bolt face.

Why is it important to clean the barrel of an AR-15 from the rear?

Cleaning the barrel from the rear forward is crucial to protect the barrel crown. The crown is vital for accuracy, and damage from cleaning from the muzzle can lead to inconsistent gas expansion and reduced precision.

What is the function of the forward assist on an AR-15?

The forward assist on an AR-15 is a manual device used to ensure the bolt is fully seated into battery. If the bolt is slightly out of position, pressing the forward assist pushes it forward, ensuring a hard lock before firing.
