NOTE: We only offer a small number of individual BCGs and limit orders to 1 unit of each finish per order. We do this to ensure availability for our upper receiver builds. If you are interested in a larger order of our BCGs, please contact us.
The BCG is the heart of the AR. We feel it is the most important component of the weapon system, so we spent a lot of time designing our BCGs and we continue to spend a lot of time inspecting and testing every single assembly.
We are very proud of our BCGs. You can learn more about our approach to the BCG as a component of the gas system in our Gas System Deep Dive series in Para Bellum University. You can learn more about the story of how our BCGs came to be in our BCG Story page. You can learn more about the general features of our BCGs in our BCG Product Page. And you can learn more about our Quality process in our Quality Promise page.
For metallurgy, treatment, and testing, the Mil-Spec is standard in all of our BCGs. Unfortunately, most consumer manufacturers fall short of the Mil-Spec standard on these fronts.
For our DLC BCG, we have thoughtfully upgraded the finish of the carrier, bolt head, and cam pin to diamond-like carbon (DLC). This upgrade offers the absolute best durability and lubricity of any finish for the BCG.
The following table includes the full nominal specifications for our DLC BCG.
