Our AR-15 BCGs are crafted from high-quality materials, such as Carpenter 158 steel or 9310 steel, known for their strength and durability. These materials ensure that our BCGs can withstand the high pressures and heat generated during firing, providing long-lasting performance and reliability.
Each BCG is precision-machined to exacting standards, ensuring proper fit and function within the AR-15 platform. Our BCGs feature various coatings, such as Nitride, Phosphate, or Nickel Boron, which enhance corrosion resistance, reduce friction, and make cleaning easier. These coatings also provide a smoother action, which can improve the overall shooting experience.
To guarantee quality and reliability, our AR-15 BCGs undergo rigorous Magnetic Particle Inspection (MPI) and High-Pressure Testing (HPT). These tests ensure that each BCG is free from structural flaws and capable of handling high-stress situations, making them suitable for both recreational and tactical use.
Our complete BCGs include the carrier, bolt, gas key, firing pin, cam pin, and retaining pin, providing everything you need for a fully operational BCG. This option is ideal for those building a new rifle or replacing an old, worn-out BCG.
For those looking to upgrade only the bolt, we offer high-quality bolt assemblies that can be easily installed into your existing carrier. These bolts are available in various calibers, including 5.56 NATO, .223 Remington, and .300 Blackout, catering to a wide range of AR-15 setups.

For competitive shooters, hunters, and gun enthusiasts alike, finding the best upgrades for your firearms is essential to maximizing performance. One of the most important components of any firearm is the bolt carrier group (BCG).
The BCG, or bolt assembly, is responsible for loading cartridges into the chamber and cycling rounds in semi-automatic or automatic weapons. This makes it critical to the effective operation of your firearms.
At 3CR Tactical, we offer an expansive selection of bolt carrier group parts to ensure high-speed performance under any operating conditions. Find the best BCG for your firearms, below; then, continue reading to learn more about the function of your bolt carrier assembly.
A bolt carrier assembly, or bolt carrier group (BCG), is the part of a firearm that houses and controls the bolt and its associated parts. The bolt is the cylindrical part of a firearm that locks into the barrel, holding the cartridge in place when fired.
It also serves as a guide for the firing pin to strike the primer of the cartridge, igniting it and causing it to fire. In some cases, bolts are removable and can be replaced with aftermarket parts.
Therefore, the bolt carrier group is essentially a complete assembly of all the parts needed to operate the bolt. These components are made from high-quality materials, such as steel or aluminum, and are designed to endure the heat and pressure of repeated gunfire.
A bolt carrier group is composed of several components that work together to operate a firearm. Each component plays an important role in the overall function and performance of the gun.
The number of parts in a BCG varies depending on the firearm model and action type. However, generally speaking, there are at least six components that must be present for a gun to properly cycle rounds:
No, the bolt carrier group of one type of weapon is not inherently compatible with other firearms models. However, the BCGs of some “related” firearms platforms may be interchangeable.
For example, AR-15 bolt carrier group parts are typically compatible with an M16 carbine, and vice versa. This is because the AR-15 is largely the civilian equivalent of the military’s Colt M16.
Upgrading and maintaining your bolt carrier assembly is vital for ensuring a long lifespan of reliable precision and performance. Although all BCGs do essentially the same thing, there is a wide range of options available on the market with varying levels of quality.
