The bolt carrier group (also known as the “BCG”) is the heartbeat of any rifle like an AR-15 or AR-10. Every time you pull the trigger on your rifle, the bolt carrier group goes to work; this is why it’s critical to have a solid AR15 BCG in your rifle.
Understanding the AR-15 Bolt Carrier Group (AR15 BCG)
The standard bolt carrier group consists of a bolt carrier, bolt, firing pin, gas key, cam pin, and firing retaining pin. Without going into too much detail, when you fire your rifle, gas moves from the barrel up through the gas tube and back into the gas key. The key moves this gas into the bolt carrier group; this unlocks the BCG and pushes it back into the buffer tube. As the bolt carrier group pushes back, the spent casing ejects and a new round chambers. The bolt carrier group quickly moves forward again and you’re back on the trigger.
That explanation simplifies the process quite a bit, but there is a lot of physics at play. The importance of the bolt carrier group can’t be understated. Think about how much you fire your rifle. Reliability is of the utmost importance when it comes to your bolt carrier group; that’s where RISE Armament comes in.
