DAG-13 Adjustable Gas Block for AKM/74-100, 13 Position-Definitive Arms

DAG-13 Adjustable Gas Block for AKM/74-100, 13 Position-Definitive Arms Available in both stand alone gas block and front sight gas block combo (separate listings). This model fits 15mm barrel journals. This model is intended for use with AKM, AK47, AK74, 100 Series AKs, and various other AKs that utilize 15mm ODs at the gas block journal. 13 position gas cup allows for fine tuning AK rifles for both recoil management, cyclic rate, and proper gassing while suppressed. Standard gas cup covers a wide range of port settings, usable in all common AK calibers. This is a restrictive gas adjustment system, it does not vent extra gas. It will prevent surplus gas from getting into the gas system and action, resulting in cleaner operation and better sound reduction while shooting suppressed. May improve accuracy by reducing amount of gas impingement inside of block on low settings. The DAG-13 system utilizes *only* one additional part over a 100 Series gas block and is extremely reliable with no fine parts that will wear out. Works with both 45-degree and 90-degree gas systems. Gas cups are easily removable for servicing and swappable with different cups for advanced end user customization. (Additional cup options and cup blanks coming soon.) Installation requires no specialty tools or skills beyond the ability to install a standard gas block. Works with standard hand guards and a plethora of aftermarket hand guards and rails. Detailed technical information and instructions will be provided with each block.
