Top 35 AR 15 BCG / AR 15 Bolt Carrier Group – Editor’s Choice

When it comes to AR-15s, the bolt carrier group (BCG) is one of the most important parts. It’s responsible for chambering, firing, and ejecting rounds, so it must function reliably and smoothly. But with so many different BCGs on the market, it can be tough to know which one is the best for your needs.

That’s why we’ve put together this guide to the best AR-15 BCGs on the market. We’ll answer common questions about BCGs, provide reviews of some of the best options out there, and give you some tips on what to look for when shopping for a BCG.

So whether you’re a first-time AR-15 owner or an experienced shooter looking to upgrade, read on for our guide to the best AR-15 BCGs.

What is a Bolt Carrier Group?

The bolt carrier group (BCG) is one of the most important parts of an AR-15. It’s responsible for chambering, firing, and ejecting rounds, so it’s critical that it functions reliably and smoothly.
The BCG is made up of the bolt carrier (which houses the bolt) and the gas key (which routes gas from the gas tube to the bolt). It also includes the firing pin, extractor, and ejector. All of these parts work together to ensure that your AR-15 functions properly.

There are two main types of BCGs: mil-spec and commercial. Mil-spec BCGs are designed to meet the specifications set by the U.S. Military, while commercial BCGs are designed for the civilian market.

  • Mil-spec BCGs are typically made from higher-quality materials and have tighter tolerances than commercial BCGs. This results in a more durable and reliable BCG, but it also means that mil-spec BCGs are usually more expensive.
  • Commercial BCGs are less expensive than mil-spec BCGs, but they’re not always as durable or reliable. That said, there are some high-quality commercial BCGs on the market that offer excellent performance.

What to Look for in an AR-15 BCG

When shopping for an AR-15 BCG, there are a few things you’ll want to keep in mind. First, consider what type of shooting you’ll be doing. If you’re planning on using your AR-15 for competition shooting, you’ll want a BCG that’s designed for reliability and precision. On the other hand, if you’re just looking for a BCG that will work well for general plinking and target shooting, you don’t need to spend as much money on a high-end model.

You’ll also want to consider the material that the BCG is made from. The two most common materials are 8620 steel and 9310 steel. 8620 steel is a low-carbon alloy steel that’s often used in carburizing applications. It’s not as strong as 9310 steel, but it’s more affordable.

9310 steel is a high-carbon alloy steel that’s often used in aerospace and defense applications. It’s stronger than 8620 steel, but it’s also more expensive.

Another thing to keep in mind is the finish of the BCG. The most common finishes are black nitride and phosphate. Black nitride is a durable finish that’s designed to resist corrosion and wear. Phosphate is a less expensive finish that’s often used on mil-spec BCGs. It’s not as durable as black nitride, but it’s more affordable.

Finally, you’ll want to consider the bolt carrier group manufacturer. There are dozens of companies that make AR-15 BCGs, and not all of them are created equal. Some manufacturers use higher-quality materials and have tighter tolerances than others. Doing some research on the different manufacturers will help you find a BCG that’s well-made and will work reliably.

Now that we’ve gone over some of the things you should look for in an AR-15 BCG, let’s take a look at some of the best options on the market.

FAQ

Can you use any BCG in an AR-15?

Yes, you can use any BCG in an AR-15. However, some are better than others.

What is the best bolt carrier group material?

The best bolt carrier group material is steel. Steel is strong and durable, and it can withstand a lot of wear and tear.

What is a BCG bolt carrier group?

A BCG bolt carrier group is a key component of the AR 15 rifle. It is responsible for chambering rounds and extracting spent cartridges. The BCG bolt carrier group also helps to keep the weapon lubricated.

There are different types of BCGs available on the market, and each has its own set of advantages and disadvantages. It is important to choose the right BCG for your AR 15 rifle to ensure optimal performance.

What are the different types of BCGs?

There are four main types of BCGs: full-auto, semi-auto, nickel boron, and titanium.

  1. Full auto BCGs are designed for use with weapons that are capable of fully automatic fire. These BCGs are typically heavier than other types and have more parts. This makes them more expensive and difficult to maintain.
  2. Semi-auto BCGs are the most common type of BCG. They are designed for use with weapons that are only capable of semi-automatic fire. Semi-auto BCGs are typically lighter than full auto BCGs and have fewer parts. This makes them less expensive and easier to maintain.
  3. Nickel boron BCGs are coated with a layer of nickel boron. This coating provides increased wear resistance and lubricity. Nickel boron BCGs are more expensive than other types of BCGs.
  4. Titanium BCGs are the lightest type of BCG. They are also the most expensive. Titanium BCGs offer the best combination of weight, strength, and durability.

What are the benefits of a BCG?

There are many benefits to using a BCG. BCGs help to increase the accuracy of the AR 15 rifle. They also make the weapon easier to control and reduce felt recoil. BCGs can also help to increase the lifespan of the AR 15 rifle.

Are bolt carrier groups drop in?

This is a common question that comes up when people are looking to buy a AR 15 bolt carrier group (BCG). The answer is, unfortunately, it depends on the BCG. Some BCGs are designed to be a drop-in, while others require some modifications to work properly. If you’re not sure whether or not your BCG is a drop-in, it’s always best to consult with the manufacturer or a qualified gunsmith.

What is the difference between a mil-spec and a commercial BCG?

The main difference between a mil-spec and commercial BCG is the diameter of the carrier key. Mil-spec carrier keys are slightly larger in diameter than commercial carrier keys. This is because mil-spec BCGs are held to tighter tolerances and therefore require a larger key to properly secure the carrier in place. Most commercial BCGs will work with either type of key, but it’s always best to check with the manufacturer to be sure.

What makes a BCG full-auto capable?

A BCG can be fully auto-capable by having a cut-out in the carrier that allows the bolt to move back and forth faster. This cut-out is called a “firing pin” and when it hits the primer on the round, it sets off the round.

Are all AR-15 BCG interchangeable?

There are a few different types of AR-15 BCG available on the market, but not all are interchangeable. You’ll need to make sure you purchase the correct BCG for your specific rifle.

What does a lightweight BCG do?

A lightweight BCG is designed to offer shooters a more lightweight option when it comes to their bolt carrier group. This can be an important consideration for those who are looking to improve the overall weight of their rifle. A lighter BCG can also help to improve the overall harmonics of the rifle, making it more accurate.

Can you use an M16 BCG in an AR-15?

Yes, you can use an M16 BCG in an AR-15. The only difference between the two is that the M16 BCG has a full-auto bolt carrier while the AR-15 BCG has a semi-auto bolt carrier.
