What is the function of a bolt carrier group?

The main purpose of the BCG in your AR 10 or AR 15 is to allow semi-automatic fire when you pull the trigger. It contains the firing pin that strikes the primer and an extractor to grab the spent shell and remove it from the chamber. After removing the empty casing, the BCG grabs another round from the magazine and feeds it into During this process, the cam pin rotates and locks the bolt so that the intense pressure from the ignition of a round doesn’t damage the weapon or the shooter. Without the bolt carrier group, the weapon would not work.

What are the benefits of a chrome-plated BCG?

Plating the metal used in a bolt carrier group with chrome is one of the selling points of Cryptic, and for good reason. Chrome is a robust material that is extremely hard and resistant to corrosion, which are both crucial aspects for a bolt carrier group. Since the BCG is directly responsible for firing, removing, and chambering rounds, it experiences intense pressure and carbon and lead exposure. Without a solid chrome plating, these conditions would wear out the BCG quickly, potentially damaging the weapon.
