Accuracy Systems new Ruger Mini gas system with precise positive click adjusting knob will actually help your rifle shoot better by reducing the harmonics that are produced when the operating rod comes in contact with your receiver during high speed cycling of the operating rod. Accuracy Systems...
As shown in the photo, I have 2 different variants of the Accuracy Systems Gen 4 Adjustable Gas Block.
The adjustment knobs are different in their diameters and the implementation of their 'click' operation.
These were acquired used and neither are functionally click adjustable. Before I start redesigning them to make the click adjustment operation function, I thought I would reach out to those who have these and ask if they have disassembled their units and readily see what original components may or may not be missing. I have my own ideas.
One knob has an integral fixed peg to engage with the dimples. The other knob has a hole (with no pin) to engage with the dimples.
Thanks for your help and observations in advance.
