https://youtu.be/8z1z1rOxUr0 There’s the link the gun looks fantastic and it has an externally adjustable regulator valve and hammer. Also can adjust for length of pull has swappable cocking lever 20 moa rail 1/2 unf threading and anti double feed comes in three different barrel lengths as well. Must be one of the most adjustable guns out there. Wonder what the shot count will be as this was not the katrans strong suit also any idea one pricing?
