Does this ACS primer twist lock in the closed position?
PER VENDOR: I'm not exactly sure what is meant by twist lock in the closed position, but I believe the answer is yes. The knob / piston assembly can be pushed in and rotated into a locked position. We have added paperwork to the 'Documents' tab on the web page on how it functions. I hope this helps.
