Kind of. I honestly thought it would be in Run & Gun, so I just wanted to get the effect in for the purpose of the stats for the story, and let the big book take care of costs. I'll get back to you on the cost, but I can't imagine it would be any different from what you'd find for the same mod in Arsenal.
I just don't happen to have my books with me to look it up. Forgot the dang thumb drive with my PDF library on it.
