Gas System Type
When it comes to choosing a BCG (bolt carrier group) for your AR15, one of the most important factors to consider is the gas system type. The gas system type of your AR15 will determine how the BCG functions and how reliable your rifle will be. There are three main gas system types to choose from: direct impingement, piston, and blowback. Each type has its own set of pros and cons, so it’s important to understand the differences before making a decision.

Direct impingement is the most common gas system type found in AR15 rifles. In a direct impingement system, gas from the fired round is directed back into the BCG to cycle the action. This system is known for its simplicity and light weight, making it a popular choice among AR15 owners. However, direct impingement systems can be prone to fouling and carbon buildup, which can affect the reliability of the rifle over time.
Piston gas systems, on the other hand, use a piston to cycle the action instead of directing gas back into the BCG. This can help reduce fouling and carbon buildup, making the rifle more reliable in the long run. Piston systems are also known for their smoother recoil and cooler operating temperatures. However, piston systems tend to be heavier and more expensive than direct impingement systems.
Blowback gas systems are a less common option for AR15 rifles. In a blowback system, the force of the fired round is used to cycle the action without the need for a gas tube or piston. This can make blowback systems simpler and more reliable than other gas system types. However, blowback systems can be harder to tune and may require more frequent maintenance to ensure proper function.
When choosing a BCG for your AR15, it’s important to consider the gas system type that will best suit your needs. If you’re looking for a lightweight and simple option, a direct impingement system may be the way to go. If reliability and smooth operation are your top priorities, a piston system might be a better choice. And if you’re looking for a unique and reliable option, a blowback system could be worth considering.
Ultimately, the best gas system type for your AR15 will depend on your personal preferences and shooting style. It’s important to do your research and consider how each system type will affect the performance of your rifle. By choosing the right gas system type for your AR15, you can ensure that your rifle will be reliable and perform at its best.
