I've posted many times that I much prefer the Latka mount to the Bixler, what a pain in the rear that thing is. As a matter of fact I sold off my personal CT9KS mainly for that reason, I've still sold a few to customers who didn't care one way or the other though as it is a really good can. Joe makes good stuff, though I really only use them for their custom work.
The nice thing is that you can get Joe to do just about whatever you want. Send him a Latka mount if that is your thing and he could thread the back to directly accept that if you don't like the Bixler mount. Or find someone that would trade. I would have traded you if I had known.
I'm very happy with my Bowers VERS 9 S on my IMI SMG. It's inexpensive and has a metric ton of mounting options available.
Does your adapter have the washers inside?
Yeah why?
I had purchased one, but looked like the washers were some kind of afterthought. I sent it back.
MK9K 3 lug is my favorite. Just wish I could get a Micro rear cap that replaces the barrel nut for it.
