Full Auto AR-15 Bolt Carrier: Everything You Need to Know

An automatic rifle is a powerful tool in the hands of a skilled operator, and it all starts with the bolt carrier group. When it comes to outfitting your AR-15 for full-auto capability, choosing the right bolt carrier group (BCG) is essential.

In this article, we'll cover everything you need to know about full auto AR-15 bolt carriers, including their benefits compared to semi-automatic BCGs and tips on how to choose one that's right for you.

Understanding Full Auto vs Semi-Auto

Before we dive into specific BCGs, let's discuss the difference between semi-automatic and fully automatic rifles. A semi-automatic firearm fires one round per trigger pull while an automatic firearm continues firing as long as the trigger is held down or until ammo runs out.

When it comes to selecting a BCG for your rifle build or upgrade, there are certain considerations that come into play based on whether you're building a select-fire weapon or simply want improved performance from your existing hardware.

Benefits of Full Auto Bolt Carriers

A full auto bolt carrier has some distinct advantages over its semi-auto counterpart. One key advantage is its increased mass which promotes smoother cycling through increased momentum when fired in sustained bursts – reducing recoil and increasing accuracy overall.

Additionally, many manufacturers construct their full auto BCs from harder materials than those used in semiautomatic variants resulting in greater durability under high stress conditions such as rapid fire exercises at long ranges where heat buildup can cause metal fatigue more quickly if lesser quality components were used instead .

Another benefit lies with compatibility – because most military-grade weaponry relies heavily upon these types of systems due largely because they provide superior reliability without sacrificing flexibility which translates into more effective use by professionals who depend on them every day during peacetime operations abroad as well domestic training exercises here at home alike!

Tips When Choosing a Full Auto Bolt Carrier

When selecting a full auto bolt carrier, there are several factors to consider. One important consideration is the materials used in its construction. Look for high-quality materials like steel or titanium that can withstand the rigors of extended use.

Another key factor is compatibility with your rifle's other components, such as your trigger group and gas system – make sure everything fits together seamlessly! It's also important to choose a BCG that balances weight with durability to ensure smooth cycling even under sustained fire conditions.

Finally, be sure to research different brands and read reviews from other users who have tried the product before you buy it so that you know what kind of performance enhancements or drawbacks each specific manufacturer might bring into play!


In conclusion, choosing a full auto AR-15 bolt carrier requires some research and careful consideration based on one’s needs. A good quality BCG will provide smoother cycling during rapid fire exercises while also being compatible with all other parts of your rifle build kit!

With this knowledge at hand plus our tips given above about what exactly makes up an ideal candidate for selection when shopping around online retailers such as Brownells or Palmetto State Armory – we hope readers feel more confident embarking upon their next upgrade project knowing precisely how much value they stand gain upgrading their weapon using only top-of-the-line components available on today’s market!


What is a full auto AR-15 bolt carrier and how does it differ from a standard bolt carrier?

A Full Auto AR-15 Bolt Carrier, also known as an M16 Bolt Carrier, is designed to be used in fully automatic rifles such as the M16 or M4. It has additional metal at the rear of the carrier that interacts with the sear in order to allow for continuous fire when holding down the trigger.

In contrast, a Standard AR-15 Bolt Carrier is used in semi-automatic rifles only. It lacks this extra metal that would interact with an automatic sear and instead relies on manual cycling of each round fired by pulling back on the charging handle after each shot.

It's important to note that simply installing a Full Auto AR-15 Bolt Carrier into your rifle does not make it fully automatic. The rest of your rifle's internals must be changed out or modified accordingly for proper function.

Is it legal to own and use a full auto AR-15 bolt carrier?

Under current US federal law, possession of any part necessary for conversion of semi-automatic firearms into fully automatic firearms (such as machineguns) beyond those parts already registered before May 19th 1986 is illegal without proper licensing from ATF/NFA. This includes Full Auto AR-15 Bolt Carriers.

Therefore, legally owning and using a Full Auto AR-15 Bolt Carrier requires you to obtain certification through NFA regulations which involves paying an annual fee along with obtaining specific forms signed by local Chief Law Enforcement Officers (CLEOs). Additionally you will need fingerprints taken along with submitting photographs and paperwork.

Are there any advantages or disadvantages associated with using full auto bolts carriers?

The main advantage associated with using Full Auto Bolts Carriers lies in their increased reliability under certain conditions such as extended firing sessions where heat can cause issues which lead other normal standard bolts carriers to fail more often.

However one major disadvantage arises especially for civilians as it is illegal to own and use a Full Auto AR-15 Bolt Carrier without proper licensing and certification.

Additionally, using a Full Auto Bolt Carrier in your rifle when firing only semi-automatic can increase wear and tear on the bolt carrier group which could lead to reliability issues down the line. It's important that you carefully consider all factors before deciding whether or not this part is right for you.

Can I install a full auto bolt carrier myself, or do I need professional help?

Installation of any firearm parts should be done by someone with experience working on firearms. This includes installing Full Auto AR-15 Bolt Carriers.

While there are numerous tutorials available online that may provide guidance, it's important that you have familiarity with all aspects of your rifle including safe handling practices prior to attempting any self-modifications.

It's always recommended that those who lack experience seek out support either from an experienced gunsmith or someone else who has gone through the process themselves.

What should I look for when purchasing a full auto AR-15 bolt carrier?

When shopping around for a Full Auto AR-15 Bolt Carrier, there are several things to keep in mind:

Firstly ensure the part is made from high-quality materials such as 8620 steel (carrier)and Carpenter 158 steel (bolt). These materials provide increased durability compared to cheaper alternatives.

Additional features such as chrome lining can also help improve reliability during extended firing sessions where heat buildup can become an issue.

Ultimately it’s best if potential buyers do their due diligence by reading reviews of different manufacturers before making any purchases. This will allow them to get an idea about what others think about these products along with comparing prices between various manufacturers.Their overall reputation among customers should be taken into consideration while making final decision regarding purchase.
