Best 308 BCG - Editor's Choice

What is 308 Bolt Carrier Group? 🚨

It refers to a specific type of bolt carrier group designed for firearms chambered in .308 Winchester or similar cartridges. The BCG is a critical component of a semi-automatic or fully automatic firearm’s operating system. It is responsible for loading, firing, extracting, and ejecting cartridges.

Best 308 BCG

How It Works 🔊

  1. 🔫 Loading: The BCG starts its cycle by moving forward, stripping a fresh round from the magazine and chambering it into the barrel.
  2. 🚀 Firing: Once the round is chambered, the BCG locks the bolt into the barrel extension. When the trigger is pulled, the firing pin strikes the primer, igniting the propellant.
  3. 💥 Unlocking: As the propellant ignites, it generates high-pressure gas that pushes the bullet down the barrel. Simultaneously, some gas is tapped through the gas port in the barrel.
  4. 🔑 Gas Operation: The gas enters the gas block and travels through a gas tube into the BCG’s gas key. The gas key directs the pressurized gas into the BCG, providing the force to cycle the action.
  5. 🏋️ Cycling: The pressurized gas pushes the BCG rearward. The carrier, connected to the bolt, moves with force, unlocking the bolt from the barrel extension.
  6. ♻️ Extraction and Ejection: As the BCG moves rearward, the extractor hooks onto the rim of the spent cartridge case. The BCG continues moving, pulling the spent casing out of the chamber and ejecting it through the ejection port.
  7. 🏭 Cocking: As the BCG reaches its rearmost position, the firing pin is reset, and the hammer or striker is cocked, preparing for the next shot.
  8. 🔄 Return to Battery: The recoil spring, located within the BCG, drives the BCG forward, pushing a new round from the magazine into the chamber.
  9. 🔒 Locking: The bolt rotates and locks into the barrel extension, securely chambering the new round.
  10. 🔫 Ready to Fire: With the BCG in its forward position and a fresh round chambered, the firearm is ready to fire again by repeating the process from step 2 onward.

      I recently assembled an AR308 and it seems to be experiencing issues with ejecting. Originally, I had a carbine stock on it and the barrel measured 20 inches. I’ve since replaced the stock with a Luth Rifle stock kit, but the issue of short-stroking persists. I’m wondering if the problem might be with the BCG.

                  I recommend to avoid NiB coating and instead consider Nitrite or DLC coating. Similarly, it is advised to avoid Aero BCG.
