Thank you for visiting Six Sigma Arms!

The AR-15 is undoubtedly one of the best rifles ever invented. Its ingenious design and modularity has caused it to be one of the most versatile rifles ever put into service. Due to its longevity and versatility there is a wide variety of configurations and options available which can be overwhelming to both new shooters and seasoned veterans. Building the perfect rifle can be overwhelming and expensive with so many products to choose from. Six Sigma Arms aims to simplify this by only offering the highest quality parts available in a configuration designed to meet your specific needs.

In our pursuit of perfection we started out by building a lower receiver that is second to none with several improvements designed to increase durability. We then developed several other products such as our Ultimate Extractor Kit. Every product we produce is hand inspected and assembled to ensure the highest quality possible.

During our pursuit, when we find a product we can't improve, we honor those manufacturers by utilizing their components in our complete rifles. Every component we offer is guaranteed to be compatible with each other. If it says "Six Sigma Arms" on the package, you can guarantee it will work with all other Six Sigma Arms components.

We also pride ourselves on customer service. We believe that each rifle should be as unique as its operator and built for the purpose you have in mind. We would be happy to talk to you about the various configurations and options available to help you build a rifle that is perfect for your needs. We want the build process to be enjoyable and informative from start to finish. We would be happy to answer any questions via email or telephone. If you ever have any questions we would be more than happy to answer them via email or telephone.

We do not offer products that we would not be proud to call our own. Every product we sell is given the same care and attention you would expect from any custom firearm. If you do choose a fully assembled rifle, we are happy to keep you fully informed during the entire build process (we will even provide pictures along the way if you desire). Having a custom rifle built should be an exciting experience and we offer every customer the time and attention they deserve. In short, we work very hard to treat our customers how we would like to be treated.

We would be happy to welcome you into the Six Sigma Arms family!
