The Definitive Arms DAG-13 series of indexable gas blocks is a very simple and robust improvement for the AK. Our original design is unlike any adjustable gas system on the market and is truly unparalleled in its features and function. The DAG-13 is a sealed system, meaning, it restricts how much gas enters the gas system instead of venting surplus gas into the action. The result is an AK that runs cooler, cleaner, more efficiently, with tons of added benefits. During suppressed use you will notice reduced or eliminated back gassing, making suppressed shooting easier on the operator. Using the DAG-13 gives you the ability to tailor the recoil and ejection of your rifle to your needs or conditions. The benefits of utilizing the DAG-13 are many, and go beyond simply allowing one to adjust the gas pressure on their AK.
