Hi there - here’s an image. I can’t find any reference to it in the user manual re dimensions. I’m starting to think I’m the only person with one at this point! Gun is about 4 years old.
How does it work, what does it interface with? Could you reverse engineer the required dimensions from the part it mates with?
If it slides into the muzzle and uses those splines to contract grooves to turn it, then I just need the circumference and the depth, width and frequency of those splines.
