Detachable Magazine bottom metal for Kimber 8400 long action magnum

[Old Salt]

I'm looking to replace the bottom metal on my Kimber 300 Win Mag Patrol Tactical rifle with a detachable magazine bottom metal setup. Correct me if I'm wrong but I think CDI Precision is no longer in business. I've googled till I dropped and can't find anyone that makes what I'm looking for, does anyone know of a person or company that can make a setup for this rifle. This rifle is no longer on Kimber's website

I am looking for one for my Advanced Tactical .308 as well.... I have absolutely no luck.
